Was wondering if there's anything like ruby's .send for htmlbars. Been trying to search for it, but can't seem to find a proper answer. Here's what I want to do:
{{"name-of-helper" arguments}}
As simple as this. Is there any trick under it to achieve this effect?
There is no built-in one or supplemented one but if you need it you can write one for yourself.
Ember includes "component" helper which allows you to dynamically build component - it's not exactly the same, but might suit your needs.

I want to find these components using Enzyme's find() facility:
<PaneWrapper data-pane="...">
<PaneWorkspaceSearch data-pane="...">
I'm currently trying this pattern, but Enzyme does not recognise it:
wrapper.find('PaneWrapper[data-pane], PaneWorkspaceSearch[data-pane]');
Any ideas?
I’d suggest using .findWhere and providing a function predicate rather than relying on string selectors here, since enzyme doesn’t yet support multiple complex selectors.
I'm new to Django and I have a BIG problem. I don't like the "url pattern" philosophy of Django.
I don't want my pages to look like
http://domain.com/object/title-of-object
I want
http://domain.com/title-of-object
and of course I will have more than one type of object.
Is there an elegant way to achieve this with Django (not using hard-coded urls)?
Thanks!
Ever wondered that, if what you want to do seems so hard to acheive, you're doing it wrong? What is so wrong with /foo/name-of-foo/ ?
I'm trying to imagine your use-case and wondering if you need 'human' URLs for only a handful of pages. If so, it would work to go with the /foo/slug-for-foo/ approach but then use the django.contrib.redirects app to support hand-written URLs that redirect to the saner, more RESTful ones?
It is possible. You'll have to create one catch-all URL pattern, for which you'll create a view that will search all possible object types, find the matching one, and process and return that. Usually, this is a bad idea.
I would like to have "realtime" like map.
My main question is:
How to use django-olwidget with openlayers OpenLayers.Strategy.Refresh?
Do I need to start back "from scratch" to use manually openlayers?
With django-olwidget, the data is on the web page so the args which define data-source, protocol.
My "second" question is about which format should I choose...
geoJSON? kml? other?
Can those formats contain openlayers point specific "style" specifications like:
{'graphic_name': 'square', 'point_radius': 10, 'fill_color': "#ABBAAB', 'stroke_color':'#BAABBA'}.
I already overriden the default map template olwidget/multi_layer_map.html to access my map object in JS. I think it should be rather simple to apply a js function on each data layers before passing it to the map.
Thanx in advance.
PS: I'm french speaker.
PS2: I asked this question as a feature request on github: https://github.com/yourcelf/olwidget/issues/89
If you're going to use regularly-refreshing data (without refreshing the page) and serialization formats like geoJSON and KML, django-olwidget won't help you very much out of the box. You might find it easier just to use OpenLayers from scratch.
But if you really wanted to use django-olwidget, here's what I would do:
Subclass olwidget.InfoLayer to create a new vector layer type that uses a network-native format like geoJSON or KML to acquire its data.
Add a corresponding python subclass to be able to use it with Django forms or whatever the use case is. You'll probably need to specify things like the URL from which the map will poll its data.
This is a lot of work beyond writing for OpenLayers directly. The advantages would be that you would get easy Django form integration with the same map.
As to which serialization format to use: I'm partial to JSON flavors over XML flavors such as KML, but it really doesn't matter much -- Django and OpenLayers both speak both fluently.
About the styling,you should take a look at the StyleMap[1] where you can set style properties according to attributes.
For the main question, I’m sorry I don’t know django-olwidget…

Regexs make me cry, so, I came here for help.
I'm looking for some tips on Find & Replace in Panic's Coda. I know the F&R
is pretty advance but I'm just looking for the best way to do this.
I'm trying to rewrite a 'template engine' (very basic) I have going on with a
webapp I'm coding in PHP (CodeIgniter).
Currently I'm calling my template like so:
$this->load->view('subviews/template/headerview');
$this->load->view('subviews/template/menuview');
$this->load->view('subviews/template/sidebar');
$this->load->view('The-View-I-Want-To-Load'); // This is the important line
$this->load->view('subviews/template/footerview');
However it's inefficient using five lines of code every time I want to
load up a different page, in every different controller. So I rewrote it like this:
$data['view'] = 'The-View-I-Want-To-Load';
$this->load->view('template',$data);
That way if I need to make any major changes to the design it can
easily be done from the template.php view file (which contains the header, menu, sidebar views etc. etc.).
However I use the previous 5-lines all over the place in many
different controllers and functions. So, my question is --- How can I
find and replace the old template engine (5 lines of code) for the new
one - substituting in the name of the view in the important, unique
line for the one in $data['view]?
Does that make any sense?! If not I'll try and rephrase! I mean, is there a way of doing this via a Regex or something? Or am I on completely the wrong lines here?
your regex will look something like this :
\$this->load->view\('subviews/template/headerview'\);\n\$this->load->view\('subviews/template/menuview'\);\n\$this->load->view\('subviews/template/sidebar'\);\n\$this->load->view\('([^']*)'\);\n\$this->load->view\('subviews/template/footerview'\);
and replace with
\$data['view'] = '$1';\n\$this->load->view('template',\$data);
I'm trying out ASP.NET MVC Framework and would like to create an ajax helper method. Basically this helper would act like ActionLink but without encoding its link text. It is rather trivial to write as an HtmlHelper, you simply have to write your own version of GenerateLinkInternal. This isn't working for AjaxHelpers though, as the ajax version of GenerateLink is indirectly calling ToJavascriptString (through GenerateAjaxScript) which is internal, thus cannot be called outside the MVC assembly. I sure can rewrite the whole thing, but it seems way overkill, is there a better way?
Ultimately, I'd like to make this helper act like BeginForm to make the link surround a block of HTML. I've not looked at it yet, but I assume that it uses ToJavascriptString too. I've searched the web and, looking through the MVC source code, I begin to wonder if I'm completely on the wrong track.
Thanks
Update: The more I look at this problem, the more I think that there's simply no solution. Whoever wrote the MVC Framework didn't think about helping people write their own helpers!
Update: I've ended up writing an helper that pretty much duplicate AjaxOptions functionality.
You could probably do this a lot easier by writing your own helper from scratch (i.e. don't make calls to any of the Html.ActionLink()/Ajax.ActionLink() methods) simply by using Url.Action() instead.
For example, it's pretty trivial to do this:
public static string NonEncodedUrl(this HtmlHelper helper,
string linkAction, string text)
{
// Get a new UrlHelper instance in the current context
var url = new UrlHelper(helper.ViewContext.RequestContext);
return String.Format("{1}", url.Action(linkAction), text);
}
You can of course extend this with overloads and extra parameters to suit your own needs.
