Admin search_fields and prepopulated_fields

[urtzai]

I get this error:

hvad.exceptions.WrongManager: To access translated fields like 'name' from an untranslated model, you must use a translation aware manager. For non-translatable models, you can get one using hvad.utils.get_translation_aware_manager.
For translatable models, use the language() method.

Hello,
Support for using translatable fields in admin is incomplete for several reasons. In short, Django admin app is not built in a way that allows external plugins such as hvad to alter its behaviour - we managed to create workarounds for some use cases, but that's limited in essence.
If you browse hvad's open issues, they are almost all about the admin :(

I guess there is some lobbying to do before serious advances can be made on that.

Hello @spectras,
Ok, I understand... :( So meanwhile, which are those workarounds? Which is the best solution in each case? I need to put at least a basic filter and prepopulated fields....

Thank you very much

Sorry for the delay, really really low on time. I hope you could find a working solution since, but anyway:

You can have a look at #187 and #303 for further information on this subject and some of the workarounds. Each admin configuration option pretty much requires a different workaround so it's hard to answer without details.

Thank you!! That worked for me!

Sorry @spectras... I tried to config a prepopulated field based on a translatable field but this workaround doesn't work anymore:

#98 (comment)

Is there any other solution?

The workaround doesn't fix this issue anymore. Anyone found a new workaround compatible with hvad==1.8.0 and django 1.11?

@VdeJong You can add an own admin template admin/change_form.html and add some custom JS :)

{% extends 'admin/change_form.html' %}
{% load staticfiles %}

{% block admin_change_form_document_ready %}
  {{ block.super }}
  <script
      type="text/javascript"
      id="django-admin-prepopulated-fields-constants"
      src="{% static "admin/js/prepopulate_init.js" %}"
      data-prepopulated-fields="[{&quot;name&quot;: &quot;slug&quot;, &quot;dependency_list&quot;: [&quot;title&quot;], &quot;allowUnicode&quot;: false, &quot;maxLength&quot;: 1024, &quot;dependency_ids&quot;: [&quot;#id_title&quot;], &quot;id&quot;: &quot;#id_slug&quot;}]"
  >
  </script>
{% endblock %}
