Need help using placeholders for auth_views in django
I created a forgot password functionality using django.contrib.auth.views which is working fine. However the styling does not go with the rest of the site. I want to use only placeholders for the form fields. But since I am using the mentioned view, i don't know how. I want to remove the Email label here and write that as a placeholder This is the general theme of the site: For the login and register pages, I am mentioning the fields separately as shown in the figure: If i try do that for my forgot-password page, I get this result with no visible fields. If I try using form.password1 and form.password2, it doesn't work and I don't get the form fields at all. Here i use only the form option. I want to have the labels as placeholders(no labels). And the other stuff removed. Here are the views used in the urls.py file: Is the view using the second form? Also is there an option for a redirect here so I can just redirect my users to login page instead of a separate page? please help -

I am new to Django and building a simple social media type app for adding and viewing posts. I am using admin side to upload profile images for users and it works well. I am yet to create a frontend to upload profile images. I am using PostgreSQL and I can query to see the correct URLs being saved in the table for profile images. But when I try to fetch these images and render, the default image (set in models.py) always renders. I am able to open the right images from admin side but Django only returns the default image.

html select tag not working in django template
This question is asked many times, but I think I am having issues with strings in the Django template I have a select tag and I want to select the default option from database <select name="category" class="form-control" required="" id="id_category"> <option value="" >--------</option> {% for cat in all_categories %} <option value="{{cat}}" {% if form.instance.category == cat %} selected {% endif %}> {{cat}}</option> {% endfor %} </select> my {{cat}} variable has value 'Django Book' and {{form.instance.category}} also have same value i.e. 'Django Book'. But it doesn't select the desired option however, I am using similar logic in another part <select class="form-control" id="client" required name="client"> <option value=" ">-----</option> {% for customer in all_customers %} <option value="{{customer.pk}}" {% if form.instance.client_id.pk == customer.pk %}selected{% endif %}>{{customer}}</option> {% endfor %} </select> but this time I am comparing ids to select the default option and it works. what is the issue in the above code?? is this issue with strings?? and how can I overcome this. Also, I would like to set strings in the value attribute in the first code example. Thanks for any help. -

Django, Only the view permission works, the rest of the permissions do not
First of all, I can't speak English well. test1 account permissions.py from rest_framework import permissions import copy class ViewPermissions(permissions.DjangoObjectPermissions): def __init__(self): self.perms_map = copy.deepcopy(self.perms_map) self.perms_map['GET'] = ['%(app_label)s.view_%(model_name)s'] class AddPermissions(permissions.DjangoObjectPermissions): def __init__(self): self.perms_map = copy.deepcopy(self.perms_map) self.perms_map['POST'] = ['%(app_label)s.add_%(model_name)s'] class UpdatePermissions(permissions.DjangoObjectPermissions): def __init__(self): self.perms_map = copy.deepcopy(self.perms_map) self.perms_map['PATCH'] = ['%(app_label)s.change_%(model_name)s'] view.py from rest_framework import viewsets, permissions, generics from .serializers import PlayerListSerializer from .models import PlayerList from .permission import ViewPermissions, AddPermissions, UpdatePermissions class ListPlayer(generics.ListCreateAPIView): permission_classes = [ViewPermissions, ] queryset = PlayerList.objects.all().filter(del_yn='no').order_by('-key') serializer_class = PlayerListSerializer class AddListPlayer(generics.ListCreateAPIView): permission_classes = [AddPermissions, ] queryset = PlayerList.objects.all().filter(del_yn='no').order_by('-key') serializer_class = PlayerListSerializer class DetailPlayer(generics.RetrieveUpdateDestroyAPIView): permission_classes = [UpdatePermissions, ] queryset = PlayerList.objects.all() serializer_class = PlayerListSerializer Through a simple test I confirmed that I can't see the list without 'view' permission. But for the rest of the permissions I get a '401 (Unauthorized)' error and it doesn't work. I have clearly given the authority right. Can you please let me know where the hell is the problem? Thanks in advance to those who answer. -

horizontal multiselect checkboxes in django admin
Hopefully this is a simple fix, although I haven't found anything through searching. I am using this code in admin.py to make my manytomany field appear as checkboxes in admin. class MyModelAdmin(admin.ModelAdmin): formfield_overrides = { models.ManyToManyField: {'widget': CheckboxSelectMultiple}, } But, I have about 10 choices, which is annoying as a vertical list. Is there a way to get the checkboxes to display horizontally or even more flexibly as 2 columns of five choices (or some other arbitrary look)?
