Form with translated fields not showed in user template

[patxisan]

Hi,

Like @russian-master in issue #243, I need to to let users to edit some fields in several languages on frontend (not in admin). But in spite of reviewing the steps in #243 thread, I have not managed to show a form with different translated fields in my frontend.

The form is defined in forms.py and I can edit translated fields in the admin without trouble. But when I try to add manually a form with translated fields into a template, the fields do not appear. Extract of code of my template, declaring manually a form field(Notice the {{ offer_form.title_en }} for translated field title_en ):

<div class="control-group">
    <label for="{{offer_form.title.html_name}}" class="control-label">
        {{offer_form.title.label}}
    </label>
    <a class="tooltip1" title="{% trans "Write a title for the offer" %}">
        <div class="controls">
            {{offer_form.title_en }}
        </div>
    </a>
    <div class="controls">
        {{offer_form.title.help_text}}
   </div>
</div>

And in my forms.py:

class EditOfferForm(forms.ModelForm):
    place = LocationEditField(Location)
    meeting_point = LocationEditField(Location, autolocate=False)
    duration = forms.IntegerField(widget=forms.HiddenInput())

    class Meta:
        model = Offer
        fields = ('title_en', 'title_es', 'resume_en', 'resume_es', 'included_price_en', 'included_price_es', 'not_included_price_en', 'not_included_price_en', 'slug_en', 'slug_es', 'place', 'meeting_point', 'duration', 'price', 'type', 'resume', 'activities')

The translated fields I want to show the forms are: "title_en" and "title_es", "resume_en" and "resume_es", "slug_en" and "slug_es", "included_price_en" and "included_price_es" and finally "not_included_price_en" and "not_included_price_es". But the form is empty after rendering the template.

My settings for modeltranslation are:

MODELTRANSLATION_DEFAULT_LANGUAGE = 'en'
MODELTRANSLATION_PREPOPULATE_LANGUAGE = 'en'
MODELTRANSLATION_FALLBACK_LANGUAGES = {'default': ('en', 'es')}
MODELTRANSLATION_AUTO_POPULATE = 'all'

What is the problem? Any ideas? Thanks in advance, Patxi.

I tried to change the declaration of EditOfferForm to inherit from TranslationModelForm instead of ModelForm:

from modeltranslation.forms import TranslationModelForm
class EditOfferForm(TranslationModelForm):
    place = LocationEditField(Location)
    meeting_point = LocationEditField(Location, autolocate=False)
    duration = forms.IntegerField(widget=forms.HiddenInput())

    class Meta:
        model = Offer
        fields = ('title_en', 'title_es', 'resume_en', 'resume_es', 'included_price_en', 'included_price_es', 'not_included_price_en', 'not_included_price_en', 'slug_en', 'slug_es', 'place', 'meeting_point', 'duration', 'price', 'type', 'resume', 'activities')

But the result is the same: The form is empty after rendering the template.

I'm experiencing the exact same problem. Does anyone know of a workaround to this problem?

So what worked for me is simply using models.ModelForm instead of TranslationModelForm.
