Let's say I wanted to showcase 2-3 clickable buttons on my homepage which will be there permanently. These are links to the css, html, and javascript tag listing pages.
Is it fine to just hardcode href=/tags/css and href=/tags/html right in my django templates/view?
I won't change them for at least a year or so, meaning I don't think I need to add a column to the tags table to distinguish them - is this common or should I try to make it somewhat dynamic? These tags are in a table but so are 1000 other tags.
Just remember to document that you did it in some place obvious, like in tagging/views.py, or maybe you have an equivalent of my When_Peter_Gets_Hit_By_A_Bus.txt, in which I document all of these types of optimizations. No, I really do have a file like that for each of my customers.

How can I personalize a list within ServiceNow?
I mean, I have this list:
But I think its very confusing to see the position on the right side.. How can I center it?
Like CSS customization or JS or something like that.. where can I find the customization form?
You can customise the position of the field content by using Field Styles.
If you mean customising the position of the field header, I have had a play around with doing this and I seem to have got it working.
If you inspect the HTML of the column header you want to target (the th tag), you'll see that there's an attribute on it called glide_type which contains in it the type of column. You can use this to create a CSS rule to target only headers of a particular type.
For example, I have a field of type decimal, and the th tag has the following attribute:glide_type="decimal". So to target that element, I could create a CSS rule like the below:
th.text-align-left.list_header_cell[glide_type="decimal"] {
text-align: right;
}
The hacky part is including that CSS so that it applies throughout the SN interface. You can use a UI Script to run some JavaScript which includes the Style Sheet. So if you put the above CSS inside a new Style Sheet (navigate to Content Management > Design > Style Sheets), and copy that new Style Sheet's Sys ID, you can create a UI Script with the below in it to include that Style Sheet on all pages:
link = document.createElement("link");
link.href = "STYLE_SHEET_SYS_ID_GOES_HERE.cssdbx?";
link.type = "text/css";
link.rel = "stylesheet";
link.media = "screen,print";
document.getElementsByTagName("head")[0].appendChild(link);
After doing that, you'll see that the Style Sheet is getting loaded on all pages, and if you've written your CSS right then you should find that the column header is now right-aligned!
As #Kirk said, performing this kind of customisation will mean that it's hard for ServiceNow Customer Support to assist if there's something you've customised getting in the way of their troubleshooting. Take this into account if you decide to implement something like this, and also thoroughly test this on a non-production instance.
In addition to the above, this solution may break in future releases as ServiceNow may decide to change the way that lists work and thus the CSS selector may no longer target the right/any element.
Hope this helps!

It's not suggested to customize any sort of CSS or JS with that, we were told that is voids your support for that section if you do so.
You could just add a few more display fields if you really desire to remove the extra white-space.
For a complete description of that (which you may know how to do):
Click the Gear icon
Then select some relevant fields from the Available section, and click the Right arrow to add them.
In Drupal you could choose in which "region" of your site you want your block displayed. You did not have to modify any php/html code in order to achieve this.
Can such a thing be achieved with Django, and if yes, how?
By block I understand a piece of html output that doesn't have it's own URL and gets displayed along side the main data. (for example a search box or a poll)
Hm you probably want to create context processor and just output from it where you want it in template?
If you want reordering of content blocks in html output inside admin then you need something to generate that output like cms. You could try something like django-fluent-contents for this without requiring big cms.
Django and Drupal shouldn't be compared like this: Drupal is a CMS, Django is a web framework.
If you want to get a somewhat similar experience, I would look at using django-cms. With this, you can create numerous templates and set placeholders within these templates (these are regions of the page like 'sidebar', 'footer', 'content area' etc.). When you go to create a new page in django-cms, you select which template you want to use (maybe a two column layout or a three column layout with a header - depending on what you have created) and then you choose what content (or plugins) you want to place within the placeholders you have created in the template. So this is a somewhat similar experience to Drupal's regions.
I'd like to categorize my tags. Here's an example of the tags I have now:
css, internet-explorer, firefox, floats
Each of those are separate tags ( 4 in total obviously ). I would like to mark the internet-explorer and firefox tags as browsers. Does django-tagging offer some sort of way for doing this or do I have to manually edit the schema?
I really don't care if I have to either tag tags or add a new column to the tags table, whichever is the easiest way in accordance with the plugin.
Interesting, I came across this problem as well and solved it like this.
I don't want to mess with the django-tagging code because it will be a pain if I wish to upgrade afterwards, so I made a new module called taggingtools. Taggingtools is for grouping tags and autocompletion in the admin interface. For the grouping I made a new model named TagGroup, this model just has a name. (for Example browsers). I also added some functions to return the tags for that group. I then added the tags for Browsers to the Browsers TagGroup. This way I can say I want all the browser tags for a certain database object. It's easy to make this, but if you can wait I can check if I can opensource it so you and others don't have to build it yourself.
The reason for this is that I want somewhat categorized permalinks. Let's say I file a bug and I want the permalink to be /css/ie-bug/ while being tagged as floats, double-margin, margin.
Would it go against the whole purpose of having tags by not tagging this as css but instead categorizing the entry? I would also not tag this as internet-explorer but instead categorize it as well.
Personally, I'd do it the same way. Permalinks (or permalink prefixes) and tags are not the same thing. Tags is very dynamic metadata that gives you the most important properties of your questions. Permalinks are (of course) static and very permanent data that shouldn't be more as a link. So using this logic it's very normal to use a different extra datamodel for permalinks, even if it introduces categories next to tags.
Just my two cents of course.
I'm working on a Django site with a basic three column design. Left column navigation, center column content and right column URL specific content blocks.
My question is about the best method of controlling the URL specific content blocks in the right column.
I am thinking of something along the lines of the Flatpages app that will make the content available to the template context if the URL matches a pre-determined pattern (perhaps regex?).
Does anyone know if such an app already exists?
If not, I am looking for some advice about the best way to implement it. Particularly in relation to the matching of patterns to the current URL. Is there any good way to re-use parts of the Django URL dispatcher for this use?
Django CMS is a good suggestion, it depends on how deep you want to go. If this is just the beginning of different sorts of dynamic content you want then you should go that way for sure.
A simple one-off solution would be something like this:
You would just need to write a view and add some variables on the end of the URL that would define what showed up there. Depending on how fancy you need to get, you could just create a simple models, and just map the view to the model key
www.example.com/content/sidecontent/jokes/
so if "jokes" was your block of variable sidecontent (one of many in your sides model instances) the urls.py entry for that would be
(r'^content/sidecontent/(?P<side>)/$,sides.views.showsides),
and then in your sides app you have a view with a
def showsides(request, side):
Sides.objects.get(pk=side)
etc...
For something like this I personally would use Django CMS. It's like flatpages on steroids.
Django CMS has a concept of Pages, Templates, and Plugins. Each page has an associated template. Templates have placeholders where you can insert different plugins. Plugins are like mini-applications that can have dynamic model-based content.
Although Django-CMS is an interesting suggestion, there are quite a few projects that do specifically what you've requested - render blocks of content based on a URL. The main one that I know about is django-flatblocks.
