When I call the $this->renderPartial() from a view it is not working at all.
Code I tried:
$this->renderPartial("_selectedalbums");
the "_selectedalbums" view is in the same directory.
What I am missing, please help.
If you are passing values to the view there might be chances that those variables may not be properly assigned or initialized.
Check if all those passing values are getting values. Also turn your error reporting on and see.
Hope it helped.
Given that the partial view is in the same view folder as the controller you are running you should check your spelling. Case sensitive file systems will require you to be exact (_selectedAlbums vs _selectedalbums).

I have succesfully used Yii2 Model & CRUD Generators to obtain some skeleton code files for my web app. Particularly, the CRUD Generator claims to have succesfully created its view files into:
<yii_root>/basic/views/<my_view_name>/*.php
which I got by leaving "View Path" field blank.
However, browsing to:
https://<my_site_FQDN>/basic/web/index.php?r=<my_view_name>/index
spits a "Not Found (#404)" error and I'm unable to find any useful info in the Yii2 debug logs.
Any idea on this matter shall be welcome.

<my_view_name> this is a terrible way of looking at this. Read about MVC.
You are creating controllers, routes are to controllers not to views. Stop looking if the views are there... look if the controller is there. You never interact with a view, you always do with a controller. So, is your controller there? are you sure you have created it?
Also what is the controller name? if you have something like ProductCategory then the correct route is
https://<my_site_FQDN>/basic/web/index.php?r=product-category/index
and not
https://<my_site_FQDN>/basic/web/index.php?r=ProductCategory/index
Edit
Ok, I see your problem, stop putting folders under other folders and so on. You created your CRUD wrong. Your controller has to be directly under controllers not under controllers/bibliografia, the same goes for the model. Delete the files and start again with CRUD as probably your namespaces are also wrong.
In my case, Yii2 consistenly writes the following with gii CRUD auto-generator.
namespace app\Controllers;
Notice uppercase 'C' for Controllers. This causes 404 error.
It should be :
namespace app\controllers
This fixed my 404 error.
I found with Yii2 (advanced template) that the generated controllers had:
namespace app\controllers;
I had to change this to:
namespace frontend\controllers;
I fixed it by capitalizing the first letter of the controller name.
Controller name should start with capital letters.
If lower case is used, Controller generator won't throw any error, but you will get not found(404) error in the browser.
this threw an error:
app\controllers\testController
this worked:
app\controllers\TestController
Its very Simple, change the namespace and please be careful while creating CRUD..
change namespace app\controllers; to namespace backend\controllers;
I'm including a partial view in one of the pages of my MVC4 site which when deployed, even after a restart of the web site and recycling of the app pool, never seems to affect the site
I'm wondering if this is caching coming into play
I ended up including the content of the partial view in the page iteself and that seems to have worked but I'd rather have the partial view as I'd like to use the view in other parts of the site
The question is, does anyone have any suggestions as to why this might be happening? I've been pulling my hair out trying to get a view to post the correct data, only to realise that some of the hidden inputs are just missing because the partial view has not been refreshed
EDIT:
Ok now I have a need to use this partial view in more than once place. On my dev environment the partial is rendering correctly. Uploading to the server doesn't seem to have any effect, but what's worse, deleting the partial view from the server also has the same issue.
My site still thinks the file is there and complains about the model type passed to the view now (I changed the model type in the view - all working fine on my local dev) - why does it still think the file is there?
I deleted one of the parent views to see if the site carried on working, but as soon as I delete any other file, the site is affected. Why is this particular file giving me trouble? It's as if the server has cached it at the file system level and is supplying the wrong file content to ASP.NET
I'm going to try renaming the file next
Ok so renaming the file appears to have worked.
I didn't try Fals suggestion but I might try that next time, strange behaviour I'm not going to try and understand why at this point!
I'm a new coder and I'm trying to interpret the Titanium code below:
var settings = Alloy.createController('settings');
What exactly is a "Controller" and when is it used? How would a "settings controller" differ from an object titled "settings"?
Any help would be great, thank you!
You might want to read Alloy Controller
and This
This will give you proper understanding of controller.
The setting you defined in createController function refers to the js file named settings while settings is just an object in any file.. But you should avoid using the same names (not necessary because sometimes it creates problems.) .
I already asked this in the Apple Dev Forum but received no replies, so I'll try here.
I'm unsure if this is a bug or whether I've missed something since I'm still very new to programming.
I have multiple view controllers and have made multiple classes. I have set the custom class "bit" of each view controller to the revelent class. When I ctrl-drag anything from the view to the relevent class header, I get the usual pop-up. I fill in the info, press connect, and BAM. It does the same kind of error whether I choose "Outlet" or "Action" It worked in the previous Xcode but I'm not sure if I've forgotten something.
The view controller and class that I added with Xcode 4 is still working beatifully.
I've tried adding the image manually but all that gave me was a SIGBART error just trying to get to the view. Again, I may have missed something, but I don't think there's much to miss is there?
Any help would be appreciated.
Just to eliminate a few things... I've deleted derived data, restarted Xcode and done a "clean". That's all I can remember that I've done.
Problem solved:
When selecting the implementation file. When I looked in the File Inspector, I found that under "Target Membership", the app name wasn't ticked. I ticked it and it now works well.
Since I didn't need to do that in Xcode 4, I suspect in Xcode 5, it doesn't do that automatically. Maybe that's a bug? I don't know if it was deliberate by Apple, but I think I'll file a bug report anyway since It's a bit of a nuisance.
I defined a class called "FilterCriteria" which has a bunch of function .m files (getAMask, getBMask, etc.) associated with it. When I create the FilterCriteria object and call the functions using it, I don't have any problems. However, recently I added another function (which, on a side note, is almost identical to another function that still works), and Matlab returns the error, "No appropriate method, property, or field getHMask for class FilterCriteria."
I've searched online for this problem, but I can't find anything. The file getHMask.m is definitely in the correct folder, so I don't understand why Matlab seems to have such a problem finding it.
Here's getHMask.m's header:
function mask = getHMask(object, quadrant, channel)
Any help would be greatly appreciated. Thanks in advance.
1) A mistake I make sometimes is not saving the file with the correct name. Make sure capital letters are in the right places etc!
2) Another layer of error checking here... You can call methods('object here') (see here) and make sure it lists the method (function) that you are trying to add to it. If it doesn't show up here you should check into the implementation of the method and make sure it's correctly being added to the class you're using for your object.
I had the same problem that's kind of suggested by Ben's bullet #2 and it was driving me crazy. Turns out MatLab wasn't loading the latest version of my class's m-file. I vaguely remembered it gave me a warning earlier about that, because there were old instances of the class in the workspace and to keep from invalidating them it said it wouldn't update the class until I cleared the workspace...
So if that's the problem, restarting MatLab will work, or you can just enter >> clear
