model - Django app structutre and circular reference -


i'm trying keep project organized, try keep splitted apps. assume blog app blogpost model. add tag app, has tag model foreign key post. if want write method get_tags(), in blog class, circular reference. bad design? maybe should not write such method on blog, or such related models should in same app?
i'm trying learn how organize (big) project. i've read lot django app concept, stil haven't found right way

the point here django automatically creates reverse lookup when create foreignkey or manytomanyfield. assuming models follows:

blogpost model 

from django.db import models  class blogpost(models.model):     title = models.charfield(_('title'), max_length=200)     slug = models.slugfield(_('slug'), unique_for_date='publish')     author = models.foreignkey(user, blank=true, null=true)     body = models.textfield(_('body'), )     publish = models.datetimefield(_('publish'), default=datetime.datetime.now)     created = models.datetimefield(_('created'), auto_now_add=true)

tag model

from django.db import models     blog.models import blogpost  class tag(models.model):     post = models.foreignkey(blogpost,related_name="tags")

now, assuming generating tags of post in view, can tags of post calling blogpost.tags_set blogpost model instance of blogpost.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
