zip() as in python for a template?

[Pei-Hsun]

Dear all,

I was wondering if there is something like zip() as in python for a template. I want to use loop for a table in a template, whose three columns contains parameters for the forms in the same row and two different sets of forms. Thus, it would be easier to zip sets of forms together to run a loop.  For example, a table would look like this:

Is it possible to do so in a template?

Thanks,

Pei-Hsun

Hi Pei-Hsun -

In this situation I would prepare a list of dicts in vars_for_template, and then loop through that list in the template.

So if I prepared a list of dicts like this:

@staticmethod
def vars_for_template(player:Player):
    rval = {}
    qlist = []
    for q in range(len(params)):
        qdict = {}
        qdict['parameter'] = 'a=='+str(q)
        qdict['question_1'] = 'Questions 1 when a=='+str(q)
        qdict['question_2'] = 'Question 1 when a=='+str(q)
        list.append(qdict)
    rval['question_list'] = qlist
    return rval

This means in the template I can loop through "question_list" like this:

<table>
{{ for q in question_list }}
    <tr><td>{{ q.parameter }}</td>
        <td>{{ q.question_1 }}</td>
        <td>{{ q.question_2 }}</td></tr>
{{ endfor }}
</table>

Basically if you have a dict in the template, you can loop through its entries and access the keys like above.

Good luck,

--Chris

Hi Chris,

sorry I did not explain my question well, but question 1 and question 2 are not literally the string I want to type. They are forms at the player level. Is it possible to loop two sets of forms?

Thanks,

Pei-Hsun
