    <p>I need to keep some settings in RAM. I created file "cache_values.py"</p> <pre><code>class CacheValue: pass </code></pre> <p>I want to use it as variable container for my needs.</p> <p>I'm writing some settings to "CacheValue" on server start:</p> <pre><code>from cms.models.pagemodel import Page from modifier.cache_values import CacheValue def cache_start_values(): CacheValue.page_publish_dates={} pages=Page.objects.all() for page in pages: CacheValue.page_publish_dates[page.pk]=page.last_publish_date CacheValue.last_publish_date=max(CacheValue.page_publish_dates.values()) </code></pre> <p>Also, when I'm saving some model - I change these settings</p> <pre><code>CacheValue.page_publish_dates[self.pk]=self.last_publish_date CacheValue.last_publish_date=max(CacheValue.page_publish_dates.values()) </code></pre> <p>But when I want to use this settings in my templates, by adding them with context processor as variables - some magic begins.</p> <pre><code>from modifier.cache_values import CacheValue def add_for_cache_info(request): context_extras = {} context_extras['page_publish_dates']=CacheValue.page_publish_dates context_extras['last_publish_date_all_pages']=CacheValue.last_publish_date if "current_page" in request.__dict__: context_extras['last_publish_date']=CacheValue.page_publish_dates[request.current_page.pk] return context_extras </code></pre> <p>In template </p> <pre><code> {{ page_publish_dates }} {{ last_publish_date_all_pages }} </code></pre> <p>Values that I see in rendered template alternates between old(before model save) and new(after model save) every time I refersh a page. 0_0 0_0</p> <p>If I save model(change value) second time - it will alterante between the oldest value and the new one.</p> <p>Why? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
