Question

I’m working on what I think is a pretty standard django site, but am having trouble getting my admin section to display the proper fields.

Here’s my models.py:

class Tech(models.Model):     name = models.CharField(max_length = 30)  class Project(models.Model):     title = models.CharField(max_length = 50)     techs = models.ManyToManyField(Tech) 

In other words, a Project can have different Tech objects and different tech objects can belong to different Projects (Project X was created with Python and Django, Project Y was C# and SQL Server)

However, the admin site doesn’t display any UI for the Tech objects. Here’s my admin.py:

class TechInline(admin.TabularInline):     model = Tech     extra = 5  class ProjectAdmin(admin.ModelAdmin):     fields = ['title']     inlines = []     list_display = ('title')  admin.site.register(Project, ProjectAdmin) 

I’ve tried adding the TechInline class to the inlines list, but that causes a

<class 'home.projects.models.Tech'> has no ForeignKey to <class 'home.projects.models.Project'> 

Error. Also tried adding techs to the fields list, but that gives a

no such table: projects_project_techs

Error. I verified, and there is no projects_project_techs table, but there is a projects_tech one. Did something perhaps get screwed up in my syncdb?

I am using Sqlite as my database if that helps.

I’ve tried adding the TechInline class to the inlines list, but that causes a

‘TechInLine’ not defined

Is that a straight copy-paste? It looks like you just made a typo — try TechInline instead of TechInLine.

If your syncdb didn’t create the proper table, you can do it manually. Execute this command:

python manage.py sqlreset <myapp> 

And look for the definition for the projects_project_techs table. Copy and paste it into the client for your database.
