[英]django-mptt children selection works on localhost but not on server
I have the same code on localhost and on server (thanks to mercurial), but it works a little bit different. 我在localhost和服务器上都使用了相同的代码(这要归功于mercurial),但是它的工作方式略有不同。 I want to render category and its subcategories in template using this code:
我想使用以下代码在模板中呈现类别及其子类别:
views.py: views.py:
def category(request, category_slug):
try:
category = Category.objects.get(slug=category_slug)
except:
raise Http404
subcats = category.get_children()
return render_to_response('catalogue.html',
{'category': category,
'subcats': subcats,
'header_template':'common/includes/header_%s.html' % flixwood_settings.CURRENT_SITE
},
context_instance=RequestContext(request))
template: 模板:
<div class='subcats'>
{% for subcat in subcats %}
{% ifequal subcat.level 1 %}
<div class="item">
<a href="{% url flixwood.views.category category_slug=subcat.slug %}"><img src="{% thumbnail subcat.image 66x66 %}" class="thumb"></a>
<a href="{% url flixwood.views.category category_slug=subcat.slug %}" class="name">{{ subcat.category }}</a>
{{ subcat.short_description|safe }}
<div class="clear_left"></div>
</div>
{% cycle '' '' '<div class="clear_left"></div>'|safe %}
{% endifequal %}
{% endfor %}
</div>
but however this code works perfectly on localhost (subcategories are rendering right) - it doesn't work on server, and the {{ subcats|length }} returns 0. I compared values from MySQL bases on localhost and on server - they are right and inheritance should work. 但是,此代码在localhost上完美地工作(子类别正确显示)-在服务器上不起作用,并且{{subcats | length}}返回0。我比较了基于localhost和服务器上MySQL的值-正确和继承应该起作用。 The funniest thing is that the same query works perfectly in manage.py shell on server.
最有趣的是,同一查询在服务器上的manage.py shell中可以完美地工作。
What the hack is wrong with it? hack有什么问题吗?
The problem was solved - it was in .pyc files, which are recreating only after apache is restarted. 问题已解决-它在.pyc文件中,仅在重新启动apache之后才重新创建。 That's why the right code in .py files didn't work.
这就是为什么.py文件中正确的代码无法正常工作的原因。
