Symfony/Sonata template path file not found and how directory structures are arranged

Question

I am using Symfony v3.3.13 and Sonata Admin Bundle 3.27.0 with TWIG v2.4.4

I have a little problem understanding how twig template paths work. I have recently needed to load a new template for a list view field in

SonataAdminBundle

.

I had to define the path as follows:

->add('coords', null, ['template' => 'SonataAdmin/CRUD/geography_point_list.html.twig']);

The geography_point_list.html.twig file was in

app/Resources/views/SonatAdmin/Crud

I also managed to get this work with the path

AppBundle::SonataAdmin/CRUD/geography_point_list.html.twig

. However then the file should be in

src/AppBundle/Resources/views/SonatAdmin/Crud

However I see in all examples that the template file path is divided by colon

:

instead of slash

/

yet, I cant get something like

AppBundle:SonataAdmin:CRUD:geography_point_list.html.twig

to work. I tried several variations and I always get

Unable to find template

. None of the following worked (I have the in both

app/Resources/views/SonataAdmin/CRUD

and

src/AppBundle/Resources/views/SonataAdmin/Crud

:

->add('coords', null, ['template' => 'App:SonataAdmin:CRUD:geography_point_list.html.twig']);



->add('coords', null, ['template' => 'AppBundle:SonataAdmin:CRUD:geography_point_list.html.twig']);



->add('coords', null, ['template' => 'AppBundle:app:Resources:views:SonataAdmin:CRUD:geography_point_list.html.twig']);



->add('coords', null, ['template' => 'App::SonataAdmin:CRUD:geography_point_list.html.twig']);



->add('coords', null, ['template' => 'AppBundle::SonataAdmin:CRUD:geography_point_list.html.twig']);

OK. So I have 2 questions:

1- Why it doesn't work? What am I doing wrong? or what may be missing? Because I can see that paths like

SonataAdminBundle:CRUD:list.html.twig

is defined in

SonataAdminBundle

and they seem to be working?

2- In template naming and locations documentation it says the correct place to put the templates is

app/Resources/views

a) Is storing templates in

AppBundle

deprecated?
b) Why it doesnt make sense to store the templates in

AppBundle

directory instead? What I don't understand is why

app

directory has

config

and

Resources

separate from

AppBundle

?

Answer 1

I think it doesn't work because you should try BundleName:DirectoryInViewsFolder:Subfolder/template.html.twig. So in your case it is AppBundle:SonataAdmin:CRUD/geography_point_list.html.twig.
Right, you can put them there.

a) In symfony 3 i don't think so.

b) I guess what in app/Resources and app/config there are global resources and configs for your application. And resources and configs for your bundle you put in src/BundleName/Resources and src/BundleName/config folders.

BTW you can also use your custom templates paths:

config.yml

twig:
    paths:
        '%kernel.project_dir%/src/YourBundle/templates': templates

YourAdmin.php

->add('coords', null, ['template' => '@templates/geography_point_list.html.twig']);

This answer is not fully correct. It was helpful for Evren Yurtesen but you should see the right answer here.
