I'm trying to add sorting to my Product:indexByTaxon action using sylius_resource_sort
I set "sortable" to true for resources. It seems though that this action doesn't support sorting at any point yet.
What would be the best apporach here? Should I replace it with modified Product:indexAction and add taxon as a criteria?
That twig extension does not work with relationship, first you need to sort on a virtual property :
{{ sylius_resource_sort('my_taxon_property') }}
After that, you need to override your repository define your own method and play with sorting. You can have a look to the method findBy()?

I am trying to use the asp-route- to build a query string that I am using to query the database.
I am confused on how the asp-route- works because I do not know how to specifically use the route that I created in my cshtml page. For example:
If I use the old school href parameter approach, I can then, inside my controller, use the specified Query to get the parameter and query my database, like this:
If I use this href:
#ulsin.custName
then, in the controller, I can use this:
HttpContext.Request.Query["ID"]
The above approach works and I am able to work with the parameter. However, if I use the htmlHelper approach, such as:
<a asp-controller="Report" asp-action="Client" asp-route-id="#ulsin.ID">#ulsin.custName</a>
How do I get that ID from the Controller? The href approach does not seem to work in this case.
According to the Anchor Tag Helper documentation, if the requested route parameter (id in your case) is not found in the route, it is added as a query parameter. Therefore, the following final link will be generated: /Report/Client?id=something. Notice that the query parameter is lowercase.
When you now try to access it in the controller as HttpContext.Request.Query["ID"], since HttpContext.Request.Query is a collection, indexing it would be case-sensitive, and so "ID" will not get you the query parameter "id". Instead of trying to resolve this manually, you can use a feature of the framework known as model binding, which will allow you to automatically and case-insensitively get the value of a query parameter.
Here is an example controller action that uses model binding to get the value of the query parameter id:
// When you add the id parameter, the framework's model binding feature will automatically populate it with the value of the query parameter 'id'.
// You can then use this parameter inside the method.
public IActionResult Client(int id)
I can't figure out how to get variables into Sphinx documents via a template. I am certainly making an elementary mistake, but while there is lots of documentation for using Jinja/Flask templates for web service and some documentation for Sphinx using it, I am having trouble doing the following. Maybe it's not possible and I'm barking up the wrong tree, but then this is fairly different from how variables work in general in web (as opposed to doc) templates?
I am working within a much larger project. Suppose in my project's conf.py I make a variable, say
LANGS = ['en', 'de', 'cn']
I know that this works because if I do the docbuild (we have a custom docbuild but I don't think it does anything really crazy other than a customized logger and eating a bunch of 'chatter') with the following line in conf.py
print len(LANGS)
it shows up during the docbuild.
But now of course I want to access this variable in my template. As far as I can tell, we override index.rst with templates/index.html, which inherits from the basic layout.html for Sphinx. And if I do
<p>We have {{ LANGS|len }} languages</p>
I get
We have 0 languages
Now, this is weird, because sometimes I can cause an error in the build by referring to variables not defined (though not consistently), so that somehow it 'knows' that the variable is defined but thinks it has length zero. Or does a "null" variable have length zero automatically?
How do I get this variable defined - or is it not possible?
What I want to do is then do something for each language in the list (make an outside link, in particular), but I figure there is no point in trying {% for %}/{% endfor %} or whatever if I can't get this working. Maybe Sphinx implements only a subset of Jinja?
Anyway, please help!
There are at least two ways to pass variables to a template:
Via html_context:
A dictionary of values to pass into the template engine’s context for all pages. Single values can also be put in this dictionary using the -A command-line option of sphinx-build.
Example:
# conf.py:
html_context = {'num_langs': len(LANGS)}
<!-- template: -->
<p>We have {{ num_langs }} languages</p>
Via the html_theme_options. This requires adding an option to theme.conf (you can create a theme by inheriting from a standard one):
[options]
num_langs = 1
Then you can set num_langs in conf.py via html_theme_options:
html_theme_options = {'num_langs': len(LANGS)}
and use it in a template:
<p>We have {{ theme_num_langs }} languages</p>
I am attempting to assign a unique id to each table row in Yii's CGridView.
Preferably something like $data->id from the database table.
I have been unsuccessful at adding an id attribute to each rendered <tr>.
Any suggestions would be most appreciated.
CGridView have an option called 'rowHtmlOptionsExpression' , you can declare like the followings to assign row an id
'rowHtmlOptionsExpression' => 'array("id"=>$data->id)',
It's better than hacking into 'rowCssClassExpression'
Good luck !
Modern solution (since Yii 1.1.13)
This is now possible to do using the rowHtmlOptionsExpression attribute, which allows assigning arbitrary HTML attributes to each rendered table row. For example:
'rowHtmlOptionsExpression' => '["id" => $data->id]'
Original answer (earlier versions)
Not directly possible because CGridView does not support it, but there are a couple of straightforward solutions that you can try.
Subclass CGridView (good)
Simply create your own class MyGridView extends CGridView and override the renderTableRow method to spit out ids on every row. Have a look at the stock implementation, which does for the class attribute exactly what you 'd like to do for the id attribute.
Use a CSS class instead (not so good)
Speaking of class attributes, the rowCssClassExpression property can be used to dynamically generate classes out of the box. IMHO this is a bad workaround, but it's there.
You could extend CGridView to add that functionality.
or be a bit hacky with rowCssClassExpression.
'rowCssClassExpression' => '\'" data-id="\' . $data->rowID'
Try the information I posted here:
How to set key value in CGrideView when grid is populated from table-view
In essence, as long as your dataprovider to the CGridview provides the data->id in a form that it understands, it will auto handle the $data->id stuff for you automatically so that it's easily available to javascript.
CGridView.rowHtmlOptionsExpression is undefined
I don't think that we can use rowHtmlOptionsExpression
I want to create a custom filter for auto_html. Where do I put the filter so I can use it?
The documentation doesn't touch on any of that. Thanks!
The approach I took was to add the code to an initializer file such as:
/path/to/your/application/config/initializers/auto_html.rb
Then you can just write something like:
AutoHtml.add_filter(:change_colours).with({}) do |text, options|
text.gsub("#FF0000", "#00FF00")
end
And call auto_html(input) { change_colours } in your model. The empty hash will take any options you care to pass to the filter.
I noticed that the latest version of slick-grid has a 'headerCssClass' attribute on the column, which would work great, except I am restricted to using slick-grid version 1.4.3.
I am extending slick-grid so as to add multiple column sort functionality and will need to set the class of each sort header accordingly. So, to re-iterate the question, does anyone know of a way to dynamically change the class of any given header in slick-grid 1.4.3?
I don't really love this solution, as it is not preferred to use JQuery to modify the slick-grid, but here goes:
var headers = $('.slick-header-columns').get(0).children;
remove any non-default class information from all the headers(i.e., $(headers).removeClass('slick-header-column-sorted'))
iterate through the columns of the slick-grid and use JQuery to add a class at the wanted column index
var header = headers[wantedColIdx];
$(header).addClass('yourClass');
I think you can do this with jQuery.
Add a blank css class with some name.
Then you can call addClass and removeClass to change the class dynamically.
http://api.jquery.com/addClass/
http://api.jquery.com/removeClass/
i.e.
jQuery('.my-class').addClass('new-header-class');
