My code above seems to only be lacking the proper embedded if conditional
statement. I am able to output the same info I need without repeating it
like in this example:
rows = db(db.store_categories).select()
for menucatchoice in rows:
if menucatchoice['subcategory'] == '':
print "Main - %s " % menucatchoice['maincategory']
if menucatchoice['subcategory']:
print "SubCategory -- %s " % menucatchoice['subcategory']
Which prints out:
Main - Animals
SubCategory -- Dogs
SubCategory -- Cats
Why can't I get it to go like that with my code above?
My code is much smaller and actually works for seeing what happens.
With the suggested code that isn't working I'm unable to see anything and
therefore unable to even debug it since it crashes immediately.
Also I was wondering if there was any actual way to see what MENU helper
actually sees, and not just using the shell. For example when you click on
the response in the ticket it shows the menu but doesn't show the actual
received output. When I view that in the shell and make adjustments such
as adding/subtracting []] or similar it is difficult to deduce what MENU
has determined as a link, false, or whatever. I have also tried other
variations such as:
menu.py
response.menu = [T('Catalog'), False, '',[]]
maininfo=db(db.store_categories.subcategory=='').select(db.store_categories.maincategory)
for maincat in maininfo:
response.menu[-1]+=([(T(maincat.maincategory)), False, 'link'])
for subcat in
db(db.store_categories.subcategory!='').select(db.store_categories.subcategory):
response.menu[-1]+=([[(T(subcat.subcategory)), False, 'link',]])
Which gets me this in the shell:
[<lazyT 'Catalog'>,
False,
'',
[<lazyT 'Animals'>,
False,
'link',
[<lazyT 'Dogs'>, False, 'link'],
[<lazyT 'Cats'>, False, 'link']]]
And for the astute observer you can see the correct way (i statically
created and works):
[(<lazyT 'Catalog'>,
False,
'',
[(<lazyT 'Animals'>,
False,
'/beta/default/Animals',
[(<lazyT 'Dogs'>, False, '/beta/default/Dogs'),
(<lazyT 'Cats'>, False, '/beta/default/Cats')])])]
You can see the slight differences so obviously I am very close. For
further clarity for myself and anyone else reading this(it has become clear
others have tried this extensively), you can see I need to have one less
bracket (if I'm correct). I say this because in the "working/correct"
version you can clearly see that the last entry "(<lazyT 'Cats'>, False,
'/beta/default/Cats')])])]" is missing the bracket that my generated one
has "[<lazyT 'Cats'>, False, 'link']]]". I realize the "()" aren't the
same however I noticed that in the shell unless the structure shows
correctly as outlined above that it does not work regardless of the "()".
You can also see that the bracket only encompasses the subcategories. So
I'm wondering how I can get that one bracket out of here (again if I'm
correct about the format). I appreciate all the code samples but, it
appears I'm doing something trivially wrong which doesn't suffice replacing
the whole thing for (in my opinion due to one bracket being off).
