Caveat to that, is there a way to have to SQLFORM top and bottom like the
picture attached?
Its more like a django kind of admin panel feature. But in web2py, can we
have the post and comment (two tables), embedded so when someone click on
the blue "plus" sign a comment box shows up and people insert the comment
on each post. Its one to many relationship (like attached picture).
If someone really trying to know what I mean by that, here is the class
definition generated for django.
class Post(models.Model):
created_at = models.DateTimeField(auto_now_add=True, db_index=True)
title = models.CharField(max_length=255)
slug = models.SlugField()
body = models.TextField()
comments = models.ManyToManyField('Comment')
def get_absolute_url(self):
return reverse('post', kwargs={"slug": self.slug})
def __unicode__(self):
return self.title
class Meta:
ordering = ["-created_at"]
class Comment(models.Model):
created_at = models.DateTimeField(auto_now_add=True)
body = models.TextField(verbose_name="Comment")
author = models.CharField(verbose_name="Name", max_length=255)
By the way, this app thats call "web2py.app.dummy.w2p", please be aware
that it has some nasty nested stuff in it. Once I installed it was crawling
all over desktop and wouldn't uninstall except from the DOS mode. Not fair.
