I have been developing with MVC for a few years and this is a nagging issue I have encountered several times. I do not like any of the ways I have handled this in the past so I thought I would ask here.
Let's say I have a series of nested DIVs on my view:
<div id="outer">
<div id="inner1">
<div id="inner2">
</div>
</div>
</div>
At runtime I want to add another element, a DIV or anchor, inside of the outer div but have it contain the inner DIVs.
<div id="outer">
<div id="newone">
<div id="inner1">
<div id="inner2">
</div>
</div>
</div>
</div>
How would you recommend handling this?
I imagine this would have more to do with JavaScript than with the server-side code. And since ASP.NET MVC comes with jQuery, you may as well make use of the wrap() function. Something like this:
$('#inner1').wrap('<div id="newone"></div>');

Previously to create Accordion controls I used to use this piece of code:
<div class="panel-group" id="accordionMessagesSetup">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordionMessagesSetup" href="#collapseMessagesSetup">
<span class="glyphicon glyphicon-chevron-up"></span>
Message Setup
</a>
</h4>
</div>
<div id="collapseMessagesSetup" class="panel-collapse collapse in">
<div>
<p style="background-color: red"> Someting ELSE in here</p>
<p style="background-color: red"> Someting ELSE2 in here</p>
</div>
</div>
</div>
</div>
or as seen here: Bootplay Live Demo
Now I still want to use my example but in this page I have a for-each loop so I need to create these at run-time.
The items I need to put variables there in order for this to work are
id="accordionMessagesSetup"
data-parent="#accordionMessagesSetup"
href="#collapseMessagesSetup"
id="collapseMessagesSetup"
How can I initialize those in a for-each loop a mode using Razor?
Imagine you have whatever property you like to do it in the model.
The biggest issue you are/will likely run into is Razor parsing. When you try to use a Razor variable in the middle of some bit of text, often Razor cannot determine where the variable name ends. For example, if you were to do something like:
<div id="accordion#Model.IdMessageSetup">
Razor thinks it needs to look for a property on the model named IdMessageSetup, when actually, you just wanted Id. The easiest way to fix this is to wrap the variable in paranthesis:
<div id="accordion#(Model.Id)MessageSetup">
Now, it's clear which part is the variable. As far as adding the # sign goes, I'm not really sure what the confusion is there. You just put it where it needs to go:
<a href="#collapse#(Model.Id)MessagesSetup">
Nothing special required.
i have created a partial view layout using bootstrap to display a single panel. whenever I call a partial view I use this layout and pass the section name on the ViewBag.
<div class="panel panel-default">
<div class="panel-heading">
#ViewBag.SectionName
</div>
<div class="panel-body">
<div class="container">
#RenderBody()
</div>
</div>
</div>
However, the issue is that inside a partial view, I may be calling another partial view using the same layout multiple times. This would result in nested panels with multiple levels.
The issue is, that I want to add a header element to the panel heading element containing the section name depending on the partial view nesting level. If we had three levels, the code would look like this:
<div class="panel panel-default main-content-panel">
<div class="panel-heading">
<h1>Section 1</h1>
</div>
<div class="panel-body">
<div class="container">
<div class="panel panel-default main-content-panel">
<div class="panel-heading">
<h2>Section 2</h2>
</div>
<div class="panel-body">
<div class="container">
<div class="panel panel-default main-content-panel">
<div class="panel-heading">
<h3>Section 3</h3>
</div>
<div class="panel-body">
<div class="container">
Some content and respective closing divs....
how could I accomplish this? An idea or solution that does not uses JS will be appreciated.
JS would certainly be the easiest way, but since you've explicitly disallowed that, the only option is to evaluate how many nesting levels there will be before they're actually rendered.
There's not a whole lot of detail here about what data structure represents these sections, but generally, you'll need to do a recursive count of the lower levels while rendering the upper level, and change the heading accordingly in the partial responsible for it. I can't give any more guidance than that without more code.
Long and short, you only get one bite at the apple when a partial is being rendered. You can't wait until the end and then modify something that happened in a previously rendered partial.
I'm using bootstrap upgrade service for upgrading from Bootstrap 2.x to 3.x
http://upgrade-bootstrap.bootply.com/
But I have a problem converting the razor syntax. For example I have:
<div class="row-fluid">
<div class="span12 form-actions">
<p>
<a class="btn" href="#Url.Action("ChooseAddItem", "Home")">Action</a>
</p>
</div>
</div>
And service returns:
<div class="row">
<div class="col-md-12 form-actions">
<p>
<a class="btn btn-default" href="#Url.Action("
chooseadditem="ChooseAddItem" home="Home">Action</a>
</p>
</div>
</div>
Look what happens to Url.Action function. This is only small example. I have a lot of files and a lot of code.
Is there any other way of converting razor views to bootstrap 3.x?

The problem you're seeing is because the service uses jQuery to manipulate the DOM and structure of your HTML. A headless browser is being used, and this changes the actual HTML content upon conversion.
I've added a new switch ("Modify nav and modal structure") to prevent this from happening, but as a result the structure of any modals and navs will not be converted to Bootstrap 3.
So, if you want to keep the Razor content the same, just uncheck the "Modify nav and modal structure" checkbox before you "Convert to Bootstrap 3" and it should work for you.
I am trying to render the outcome of an action into a modal (twitter bootstrap). Unfortunately I do not get this to work.
Before I was generating a link within an each iterator:
<g:link action="perform" id="${exerciseInstance.id}">
<h2>${fieldValue(bean: exerciseInstance, field: "title")}: (${exerciseInstance.questions.size()} Questions)</h2>
</g:link>
Instead of rendering a complete new site I rather want the quiz to be presented in a modal. Therefore I tried a simple twitter bootstrap modal example:
<a data-toggle="modal" href="#myModal" class="btn btn-primary btn-large">${fieldValue(bean: exerciseInstance, field: "title")}</a>
<div id="myModal" class="modal hide fade" style="display: none; ">
<div class="modal-header">
<h3>Test</h3>
</div>
<div class="modal-body">
--> This is where the content should go <--
</div>
<div class="modal-footer">
Close
</div>
</div>
What is the best way to achieve this?
Asking for the "best way" on SO is a dangerous game. There probably isn't a best. Just different approaches. I'll give you one that I use utilizing jQuery's $.load() function.
$("#myModal .modal-body").load(url);
It really is that simple. Obviously, adjust your load() function if you need to pass in parameters, provide a callback function, etc. Your controller's action would just render a template containing the HTML you want in your modal-body. This isn't really even Grails specific. This approach would work with any server side tech.
In rails, I'm used to use the yield/content_for to site mesh. (http://guides.rubyonrails.org/layouts_and_rendering.html#using-content_for)
I can't find in Grails documentation a way to do this... Could you help me?
EDIT
Here is the situation:
I have a layout containing this:
<body>
<div id="wrapper">
<div id="container">
<div id="header">
<g:render template="/layouts/header"/>
</div>
<g:render template="/layouts/menu"/>
<div id="container-homepage">
<g:layoutBody/>
<div id="subfooter">
<div id="content">
<div id="left">
<div id="logo_sub_header"></div>
</div>
<div id="right"></div>
</div>
</div>
</div>
</div>
</div>
</body>
And I want to be able to add a html snippet (search tool bar for example) juste above the container-homepage div. A partial could do the trick.. if this search tool bar was always the same. The thing here is that this search bar depends on the page i'm visiting.
I could also just change the position of the container-homepage div to put it directly into the view, and not the layout, but then i'll have to to it in ALL the views, and that's not DRY.
Any ideas?
Regards,
I think you have two solutions:
the g:render tag is the best option if your content block will not change based on a custom page.
Anyway I would take a look ah this link
http://grails.org/Content+Blocks
because g:pageProperty it is the most elegant and flexible solution.
Perhaps the g:render tag is what you're looking for? It allows you to render a template anywhere within your view (including in other templates). You can also pass in a model for the template to use.
Note the section at the bottom of that page on naming conventions -- template view gsp filenames should begin with an underscore (though that underscore is not supplied in the render tag). There's mos def a way to override this, but things work automagically if you put the underscore there.
