Hello folks, I am new to both Python and Django. And the story is a little long. So, please bear with me.
Recently I created a site named djangoSite to practice the Django framework. The first thing I want to do is to create a SQLite database to hold global data of the site. As simple as it sounds, the actual process I went through wasn't so simple. First, I created an apps/ subdirectory under djangoSite/ to hold all potential applications I may have. Then, I created an empty file __init__.pyto makeapps/a package.Then, I wanted to create an app global to make models for holding global data. I tried the following to do this. djangoSite/ >$ cd apps apps/ >$ ../manage.py startapp global It turns out the app global was created under djangoSite/ rather than under apps/. So, here is one question. *How do I create a sub-app under apps/ with manage.py?* Anyway, I didn't stop there. I moved the folder global/ into apps/. I assumed that this would make global a subapp of apps, so that something like this would work under manage.py shell: import apps.global. However, I didn't test it right after moving the folder global/, which I should have. Instead, I proceeded and created a model in apps/global/models.py named NavItem. Then, I added 'djangoSite.apps.global' to settings.INSTALLED_APPS. Then, I added a SQLite3 database 'global' in settings.DATABASES, and created a Python file dbrouter.py under djangoSite/, in which I created a class DBRouter to route the databases. Accordingly, I added DATABASE_ROUTERS = ['djangoSite.dbrouter.DBRouter'] to settings.py. Here is another question. When creating the class DBRouter, I basically copied the example (only the master class) in the Django documentation Multiple Databases<https://docs.djangoproject.com/en/dev/topics/db/multi-db/#topics-db-multi-db-routing>. It seems to me the newly created routing class, which is DBRouter in my case, inherits a class named object, because of this statement: class DBRouter(object). However, the example in the document I mentioned earlier doesn't import anything at all, so the question is *where this class 'object' come from*? Anyway, I kept moving. Under djangoSite/, I ran ./manage.py validate, which gave 0 error. Then, I ran ./manage.py syncdb. And I got a bunch of errors. I suspected that the database routing may not work. So, commented out the DATABASE_ROUTERS settings, and ran ./manage.py syncdb again. This time, it went through without errors. Now I am guessing that I need to import something to make DBRouter work. So I started tracking down the problem. I invoked manage.py shell, and wanted to create an instance of NavItem. I tried the following import statements, but none of these worked. All of the them get a syntax error. Here thery are. >>> from apps.global.models import NavItem File "<console>", line 1 from apps.global.models import NavItem ^ SyntaxError: invalid syntax >>> from global.models import NavItem File "<console>", line 1 from global.models import NavItem ^ SyntaxError: invalid syntax >>> from djangoSite.apps.global.models import NavItem File "<console>", line 1 from djangoSite.apps.global.models import NavItem ^ SyntaxError: invalid syntax >>> from global.models import NavItem File "<console>", line 1 from global.models import NavItem ^ SyntaxError: invalid syntax Now I am running out of ideas about what went wrong. I know this is a bit long, so I really appreciate your help. Thank you very much. Jim , I also created and an subdirectory apps to hold all my django applications. I created an empty file __init__.py to make the folder apps a package. Then, I meant to create an app named global to hold global data of the site. -- You received this message because you are subscribed to the Google Groups "Django users" group.
