Hi All -
I'm a bit of a newbie with django, but I think I bit off more than I
can chew.
I'm trying to build a brick wall via html table, tds and colspans:
0. The "bricks" will lay out as follows
| -- | 20 | 21 | 22 | ----- |
| 16 | 17 | 18 | 19 | -- |
| -- | 12 | 13 | 14 | 15 |
| 8 | 9 | 10 | 11 | -- |
| -- | 4 | 5 | 6 | 7 |
| 0 | 1 | 2 | 3 | -- |
1. I have a list of objects called storys from the database
2. I've generated a list of rows via range and reverse. ie. [5, 4,
3, 2, 1, 0]
3. I've generated a list of cols via range. ie. [0, 1, 2, 3]
4. I've registered a custom tag to calculate an offset into my story
list given a row and col
offset = row * BRICK_PER_ROW + col
5. I pass the rowlist, collist and storylist to my template
Question:
So, as I loop through rows and columns, how do I use my custom tag to
find and
index into my story list.
I know I am describing the problem rather than showing you the code,
but most
everything I've tried returns a "Could not parse the remainder" error
and most
custom tag examples on the web feel like custom filter examples to me.
I don't know how to pass the parameters (row and col) to my custom
tag?
{{ story.offset<given row and column somehow?>.attribute }} where
"offset" is my custom tag?
Trial and error and web searches aren't helping this time, so I place
myself at the mercy
of the court. Please go gentle with me. Django has been supercool so
far, but this "no business logic rule" in my presentation layer has
got me baffled.
Thanks in advance for your support and counsel.
Sincerely,
Pete
