I am a Fedora 20 user. To solve this: Install sqlite-devel package, using: yum install sqlite-devel After installing,recompile python from the source using: ./configure make && make install For multiple versions of Python, use altinstall instead of install.
To change the redirect destination after save in the admin, you need to override response_add() (for adding new instances) and response_change() (for changing existing ones) in the ModelAdmin class. See the original code in django.contrib.admin.options. Quick examples to make it clearer how to do this (would be within a ModelAdmin class): from django.core.urlresolvers import reverse … Read more
Use request.data instead of request.body. request.data does not read the data stream again.
from django.db.models import Count top_users = User.objects.filter(problem_user=False) \ .annotate(num_submissions=Count(‘submission’)) \ .order_by(‘-num_submissions’)[:3] You didn’t mention problem_user in your example model code, but I’ve left it in assuming that it is a BooleanField on User.
Variable lists, also known as a many-to-one relationship, are usually handled by making a separate model for the many and, in that model, using a ForeignKey to the “one”. There isn’t an app like this in django.contrib, but there are several external projects you can use, e.g. django-photologue which even has some support for viewing … Read more
You can convert it into string by using JSON and store it as string. For example, In [3]: json.dumps([[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]]) Out[3]: ‘[[1, 3, 4], [4, 2, 6], [8, 12, 3], [3, 3, 9]]’ You can add a method into your class to convert it automatically … Read more
Based on x0nix’s answer I did some experiments. It seems like returning an empty dict from get_model_perms excludes the model from index.html, whilst still allowing you to edit instances directly. class MyModelAdmin(admin.ModelAdmin): def get_model_perms(self, request): “”” Return empty perms dict thus hiding the model from admin index. “”” return {} admin.site.register(MyModel, MyModelAdmin)
F objects. from django.db.models import F stale_activities = Activity.objects.filter(updated__gte=F(‘added_toSolr_date’))
Overriding __init__() would cause code to be executed whenever the python representation of object is instantiated. I don’t know rails, but a :before_created filter sounds to me like it’s code to be executed when the object is created in the database. If you want to execute code when a new object is created in the … Read more
You can subclass DjangoTestSuiteRunner and override setup_databases and teardown_databases methods to pass. Create a new settings file and set TEST_RUNNER to the new class you just created. Then when you’re running your test, specify your new settings file with –settings flag. Here is what I did: Create a custom test suit runner similar to this: … Read more
