Render a JBuilder view in html view - ruby-on-rails-3

I've created a json view with JBuilder. But I want to preload this into a data object, so Backbone has access to the data early on without fetching for it.
How can I render the list.json.jbuilder view into my list.html.erb view?
Normally without jbuilder, I'd do something like this:
<div data-list="<%= #contents.to_json %>"></div>

render, when called from within a view, returns a string rendering of the passed template or partial; you can embed that string into your view as you like. Note though that:
You have to append your template name with the type suffix/extension. If you don't, Rails may get confused about which template file you're calling; ie: it might choose list.html.erb instead of list.json.jbuilder. If you're making this call from list.html.erb, trying to render list.html.erb results in infinite recursion and a SystemStackError. Using the :format option for render doesn't appear to work.
You have to specify the qualified path to the template; it won't find the right template for "list.json" just because list.json.jbuilder resides in the same directory as list.html.erb.
You need to pass the output of the render call through raw; otherwise, it will get escaped when it gets embedded into the view.
So, for your example, you might write this, assuming your templates were in /app/views/foo:
<div data-list="<%= raw render(:template => "foo/list.json", :locals => { :contents => #contents }) %>"></div>

Render something on specific page

So I got this base.vue layout, I am having here my top nav and rest of content, I am wondering if it's possible I add input type search in the sticky div and render it only on specific route pages? For e.g I dont want to have the search bar on every page, but only to appear when I got onto a view with users, where I can filter them.
.sticky.top-0.h-14.bg-white-200.shadow.px-8.flex.items-center
input(type="search" placeholder="search)
.container.max-w-full.mx-auto.p-8
router-view
In your script add a computed property that checks if the current route path is /users :
computed:{
isUsersPath(){
return this.$route.path==='/users'
}
}
then use it in template like :
div(v-if="isUsersPath").sticky.top-0.h-14.bg-white-200.shadow.px-8.flex.items-center
input(type="search" placeholder="search)
.container.max-w-full.mx-auto.p-8
router-view

Ng-grid with external data and TypeScript: compile error "Cannot set property 'gridDim' of undefined"

Update #1: after the fix I commented about, now my app starts but the grid is not rendered except for its bounding box and filter button and popup. Yet, I get no error from the console, and as far as I can arrive with the debugger, I can see that data got from the server are OK. If I use Batarang, I can see the scope corresponding to my model, correctly filled with items. I updated the downloadable repro solution accordingly. Could anyone explain why ng-grid is not updating here?
I'm starting to play with ng-grid and TypeScript and I'm finding issues as soon as my test app starts up. See the bottom of this post for a link to a full test solution. Surely I have made tons of errors even in these few files, but I'd like to have something to start with and learn more step by step.
The MVC app has two client-side applications:
app.js for the default view (Home/Index). No typescript here, and the whole code is self-contained in this single file. The code is derived from the paging example in the ng-grid documentation and tries to stay as simplest as possible.
MyApp.js for the more realistic sample in another view (Home/Model). This sample uses services, models and controllers and its JS code is compiled from TypeScript. To keep things simple, I'm just storing these components under Scripts/App, in folders for Controllers, Models and Services, and each file contains just a single class or interface. The generated JS files are manually included in the view.
app.js works, except that it has issues with filtering. I posted about these here:
Server-side filtering with ng-grid: binding issue?
MyApp.js has startup issues with ng-grid. As soon as the app starts, a TypeError is thrown in the grid binding:
TypeError: Cannot set property 'gridDim' of undefined

The only similar issue I found by googling is https://github.com/angular-ui/ng-grid/issues/60, but it does not seem to be related to my case as there the grid options were setup too late.
The server side just has an API RESTful controller returning server-paged, sorted and filtered items.
You can find the full repro solution here (just save, unzip and open; all the dependencies come from NuGet); see the readme.txt file for more information:

Just start the app and click MODEL in the upper right corner to run the TypeScript app throwing the error. The whole app is composed of 1 controller, 1 service and 1 model.
For starters like me, it would be nice to have a simple working example like this one. Could anyone help?
This error means gridOptions has not yet been defined by the time that Angular attempts to parse ng-grid="yourArray", where yourArray is the same array supplied to gridOptions. I had the same problem after refactoring a previously working ng-grid.
So gridOptions must be defined before the element which has ng-grid="yourArray" attribute applied to it (rather than within that element's own controller).
I resolved this by defining gridOptions in an outer element somewhere (on global/app scope, for instance).
P.S. Maybe there is a better way, but this has worked for me.
Where you are adding data to your grid?
If you are writing $scope.myGrid={data:"someObj"}; in a success call then it won't work.
See the below reason:(which is listed in https://github.com/angular-ui/ng-grid/issues/60)
You can't define the grid options in the success call. You need to define
them on the scope in your controller and then set the data or column
definitions, etc... from the success call.
What you have to do?, First is to see how this made ​​your project and revizar if your queries or data access, the beams through a service, if so this I must add the file that manages routes app, the client side.
remain so.
'use strict';
angular.module('iseApp', [
'ngCookies',
'ngResource',
'ngSanitize',
'ngRoute',
**'ngGrid',**
'campaignServices',
'dialinglistServices',
'itemServices'
])
.config(function ($routeProvider, $locationProvider, $httpProvider) {
$routeProvider
As you are adding your ng-grid in a directive, you have to make sure the grid options are loaded before it tries to parse your html.
You could set a boolean in your link function :
scope.isDirectiveLoaded=true;
And then, in your template, use a ng-if :
<div ng-if="isDirectiveLoaded">
<div ng-grid="myGrid"/>
</div>
I got to the same issue, empty grid was rendered.
The way I got to it in the end was to setup my this.gridOptions in the constructor of the controller, within the component. In the options everything is referenced with $ctrl like this. So the data references $ctrl.gridData. gridData is specified as a property in my component controller. $ctrl is not defined as a property.
This was done in the constructor before the data was loaded. this.gridData was defined after in the constructor and then populated later in another function. The options were defined first, I think this is important from some things I read.
For the event hooks pass null instead of $scope.
this.gridOptions = {
enableGridMenu: true,
minRowsToShow: 25,
rowHeight: 36,
enableRowHashing: true,
data: '$ctrl.gridData',
rowTemplate: this.$rootScope.blockedRowTemplate,
onRegisterApi: ($ctrl) => {
this.gridApi = $ctrl;
this.gridApi.colMovable.on.columnPositionChanged(null, (colDef, originalPosition, newPosition) => {
this.saveState();
});
this.gridApi.colResizable.on.columnSizeChanged(null, (colDef, deltaChange) => {
this.saveState();
});
this.gridApi.core.on.columnVisibilityChanged(null, (column) => {
this.saveState();
});
this.gridApi.core.on.sortChanged(null, (grid, sortColumns) => {
this.saveState();
});
this.gridApi.core.on.filterChanged(null, (grid, sortColumns) => {
this.saveState();
});
}
};
In the row template I was referencing functions defined in my component. Before conversion to a component I referenced functions like this:
ng-click="grid.appScope.jumpToExport(row.entity);"
After conversion to the component I needed to add the $ctrl before the function name like this
ng-click="grid.appScope.$ctrl.jumpToExport(row.entity);"
And this is how the component is referenced in the html
<div ui-grid="$ctrl.gridOptions" ng-if="$ctrl.gridData.length != undefined && $ctrl.gridData.length > 0" class="data-grid" ui-grid-save-state ui-grid-resize-columns ui-grid-move-columns></div>

Multiple/nested appllicationHost

Drupal's Nuget sample is turning out to be nice, and the docs helpful..
So far, figured out that index.html contains the host named as applicationHost:
<div id="applicationHost"></div>
and was filled because main.js loaded the shell.js module:
router.mapNav('welcome');
...
app.setRoot('viewmodels/shell', 'entrance');
that, upon view activation routed to the welcome module, therefore welcome view:
activate: function () {return router.activate('welcome');}
Great.
What I'm now trying to figure out is how to have nested 'applicationHost' containers, loading views into either one independendantly.
An example might be
router.mapNav('settings');
router.mapNav('settings/mailserver'); //but this one render within an inner container.
router.mapNav('settings/messages'); //but this one render within an inner container.
...
app.setRoot('viewmodels/shell', 'entrance');
So that settings.html is rendered, with another container within it and it's viewmodel some thing akin to:
//As restauants view comes in, it sets it's inner view to something
activate: function () {return router.activate('settings/mailserver');}
Related to this first question -- if there is a link on another page to settings/messages, or settings/mailserver, how do I ensure that the parent settings is ensured to be visible first?
Thanks very much.
You would like to use Visual Composition.
e.g.
<div>
<div data-bind="compose:'viewmodels/header'"></div>
</div>
Please refer:

I think you're looking for child routers http://durandaljs.com/documentation/Using-The-Router.html

Pass an object to a widget in template

I have a Dojo UI widget that has a widget embedded within it. I need to pass an object to this embedded widget for it to set itself up correctly, but I'm not sure how to do it.
I have been templating in the embedded widget in the template for the wrapper widget, for example:
...<div class="thing"
data-dojo-type="mycompany.widgets.ComplexEmbeddedWidget"
data-dojo-props="stuff: '${stuff}'"></div>...
but this doesn't seem to work, I guess the data is passed as a string maybe?
I'm pulling out this data by setting it to a property in the embedded widget and then referencing it in my postMixInProperties function.
Doubtless this is the wrong approach, what should I be doing to set up an embedded widget such as this?
I think if you are going to use this approach, you want to convert the javascript object json before it is passed to the templated embedded widget.
You can easily do this by requiring 'dojo/json' and doing
this.stuff=jsonModule.stringify(this.stuffAsObject);
As you have already discovered, if you are setting more complex properties, programmatic instantiation is probably the way to go.
If your mycompany.widgets.ComplexEmbeddedWidget is desperate to have the object 'stuff' set allready once it is initialized (in constructor), then im not sure this approach will do, however a simple fix could be removing the ' quotes around ${stuff}?
What happens is basically that you derive the widget with dijit/_TemplatedMixin. This in turn, during buildRendering, calls _stringRepl on 'this' (the widget). I am not completely certain of the flow, since youre working with WidgetsInTemplate..
lets as example, set a widgets attribute to an array via markup:
<div
data-dojo-type="dijit.form.Select"
data-dojo-props="options:[ 'val1', 'val2']">
</div>
As you see, no quotes around the value - or it will render as a string. Lets then change your ComplexEmbedded template to
dojo.declare("exampleName", [_WidgetsInTemplateMixin, _TemplatedMixin], {
templateString: '<div class="outerWidgetDomNode">
...
<div class="thing"
data-dojo-type="mycompany.widgets.ComplexEmbeddedWidget"
data-dojo-props="stuff: ${stuff}"></div>
...
'
});
To instantiate the ComplexEmbeddedWidget.stuff with an object, this needs to be a string. _Templated uses dojo.string.substitute, which probably would fail if given deep nested object.
Markup example:
<div data-dojo-type="exampleName" data-dojo-props="stuff: '{ json:\'Representation\', as:\'String\'}'"></div>
Or via programmatic
var myObj = { obj:'Representation', as:'Object' };
var anExampleName = new exampleName({
stuff: dojo.toJson(myObj) // stringify here
}, 'exampleNode');
Lets know how goes, ive been wanting to look into the presendence of flow with this embedding widgets into template stuff for a while :)
You can programmatically insert widgets. This seems to be be the way to go if the inserted widget requires JavaScript objects to be passed to it.

Yii Retrieve and store in a variable a renderPartial file

I have a php file under protected/views/directory_controller_name with formatting like that
<p>
<?php echo $model->title;?>
</p>
...
I display the file with classic method in the controller :
$this->render('filename',array('model'=>$model));
But know, I need to send an email with the same template/layout so I want to store the render of the file in an variable like
$msgHTML = $this->renderInternal('_items', array('model'=>$model));
But it doesn't work!
How can I get render view from a file and store in a variable?
Is it possible?
I don't want to use:
$msgHTML = '<p>'.$model->title.'</p>'
...
Because the file is very long and I don't want to duplicate code!!!
Don't use the renderInternal method, use renderPartial instead. Render internal is low level method and should not be used in such context. To catch the output just set the $return parameter to true:
<?php $output = $this->renderPartial('_subView', $dataArray, true); ?>
$msgHTML = $this->renderInternal('_items', array('model'=>$model), true);
http://www.yiiframework.com/doc/api/1.1/CBaseController#renderInternal-detail
I might be missing something, but can't you just use regular render() with the return argument set to true? Then you can just use a view 'name' instead of knowing the path. (And unless my trusty stack trace logger is broken, renderFile and renderInternal take the same fully qualified path argument. At least I can see renderPartial() passing the full path to my view file to renderFile.)
you can do this with these ways
1) if you want to get the output with header and footer (i.e ) full layout then do this
//add true in the last parameter if you want a return of the output
$htmloutput=$this->render('_pdfoutput',array('data'=>'nothing'),true);
2) similarly if you don't want to get the layout files just use renderpartial in the same way
$htmloutput=$this->renderpartial('_pdfoutput',array('data'=>'nothing'),true);
you will get the html of files in the variable . use this anywhere
