in my controller:
def view_searches:
if db(db.post).isempty():
db.post.insert(message="Hi, it's" +' ' +auth.user.first_name+' '+
'loging in...')
form = SQLFORM(Post, formstyle='table3cols',)
if form.process().accepted:
pass
long code...
replies = db(db.answers.author == auth.user.id
).select(db.answers.ALL)[-5:5]
return dict(form = SQLFORM(Post, formstyle='table3cols',).process(),
replies = db(db.answers.author == auth.user.id
).select(db.answers.ALL)[-5:5])
html page:
{{extend "layout.html"}}
{{=LOAD('replies','view_searches.load',ajax=True)}}
error message on loading view_searches.html:
invalid controller (replies/view_searches)
This is how far I've come
