In order to achieve this and have a usable ‘All’ link in your sidebar (ie one that shows all rather than showing pending), you’d need to create a custom list filter, inheriting from django.contrib.admin.filters.SimpleListFilter and filtering on ‘pending’ by default. Something along these lines should work: from datetime import date from django.utils.translation import ugettext_lazy as … Read more
If you want it to take effect only in admin, and not globally, then you could create a custom ModelChoiceField subclass, use that in a custom ModelForm and then set the relevant admin class to use your customized form. Using an example which has a ForeignKey to the Person model used by @Enrique: class Invoice(models.Model): … Read more
That’s not something you do as a field. Even if that syntax worked, it would only give the value when the class was defined, not at the time you access it. You should do this as a method, and you can use the @property decorator to make it look like a normal attribute. @property def … Read more
In your save you have to have the argument commit. If anything overrides your form, or wants to modify what it’s saving, it will do save(commit=False), modify the output, and then save it itself. Also, your ModelForm should return the model it’s saving. Usually a ModelForm’s save will look something like: def save(self, commit=True): m … Read more
For example, your apps are app and app2 and there are A, B models in app and there are C, D models in app2. you want to see only app.A and app.B and app2.C from django.db import models class TaggedItem(models.Model): tag = models.SlugField() limit = models.Q(app_label=”app”, model=”a”) | models.Q(app_label=”app”, model=”b”) | models.Q(app_label=”app2″, model=”c”) content_type = … Read more
You can override get_queryset method in your model admin class. class MyModelAdmin(admin.ModelAdmin): def get_queryset(self, request): qs = super(MyModelAdmin, self).get_queryset(request) if request.user.is_superuser: return qs return qs.filter(author=request.user) Note in Django<=1.5 the method was named just queryset.
When you save a model via admin forms it’s not an atomic transaction. The main object gets saved first (to make sure it has a PK), then the M2M is cleared and the new values set to whatever came out of the form. So if you are in the save() of the main object you … Read more
I loved Greg’s solution to this problem, but I’d like to point that you can do the same thing directly in the admin: from django.db import models class CustomerAdmin(admin.ModelAdmin): list_display = (‘number_of_orders’,) def get_queryset(self, request): # def queryset(self, request): # For Django <1.6 qs = super(CustomerAdmin, self).get_queryset(request) # qs = super(CustomerAdmin, self).queryset(request) # For Django … Read more
Sure. In your model class add a method like: def image_tag(self): from django.utils.html import escape return u'<img src=”https://stackoverflow.com/questions/16307307/%s” />’ % escape(<URL to the image>) image_tag.short_description = ‘Image’ image_tag.allow_tags = True and in your admin.py add: fields = ( ‘image_tag’, ) readonly_fields = (‘image_tag’,) to your ModelAdmin. If you want to restrict the ability to edit … Read more
Thanks to gpilotino for giving me the push into the right direction for implementing this. I noticed the question’s code is using a datetime to figure out when its live . So I used the DateFieldFilterSpec and subclassed it. from django.db import models from django.contrib.admin.filterspecs import FilterSpec, ChoicesFilterSpec,DateFieldFilterSpec from django.utils.encoding import smart_unicode from django.utils.translation import … Read more
