本文介绍了如何在Django / python中每行循环三列?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
< table>
将TR>< TD> VALUE1< / TD>< TD> VALUE2< / TD>< TD> VALUE3< / TD>< / TR>
将TR>< TD> VALUE4< / TD><< TD>值5< / TD>< TD> VALUE6< / TD>< / TR>
< / table>
任何人都知道该怎么做?
语法错误
TemplateSyntaxError at /
'for'语句应该使用格式'for x在y'中:对于范围(0,len(all_products_list),3)
解决方案
有一个divisibleby标记。所以你可以做一些丑陋的事情,如:
< table> ;< TR>
{%for form in form%}
< td> {{field}}< / td>
{%if forloop.last%}
< / tr>
{%else%}
{%if forloop.counter | divisibleby:3%}
< / tr>< tr>
{%endif%}
{%endif%}
{%endfor%}
< / table>
或者,你可以给你的表单类一个 table_print
返回一个html字符串的方法(包装在 mark_safe
中)。
I would like to display data, three columns per row during my for. I would like my result to look like the following:
<table>
<tr><td>VALUE1</td><td>VALUE2</td><td>VALUE3</td></tr>
<tr><td>VALUE4</td><<td>VALUE5</td><td>VALUE6</td></tr>
</table>
Anyone know how to do it?
Syntax Error TemplateSyntaxError at /
'for' statements should use the format 'for x in y': for i in range(0, len(all_products_list), 3)
解决方案
There's a divisibleby tag.
So you can do something (ugly) like:
<table><tr>
{% for field in form %}
<td>{{ field }}</td>
{% if forloop.last %}
</tr>
{% else %}
{% if forloop.counter|divisibleby:"3" %}
</tr><tr>
{% endif %}
{% endif %}
{% endfor %}
</table>
Alternatively, you could give your form class a table_print
method that returns a html string (wrapped in mark_safe
).
