rails 3 render partial with params

阅读更多关于 rails 3 render partial with params

I'm having a problem passing some parameters to a partial. No matter what I've tried the params don't pass when the partial is rendered. I am using a jquery tabbed layout, and each tab displays work orders in a particular status and also based on a range of dates. I am using the params :sort_filter and :status_filter to accomplish this. My original code is here, but I want to change this to render partials in the link_to's instead of the way it's listed here: <ul> <li><%= link_to "Active", work_orders_path(params.merge({:status_filter => "A", :sort_filter => params[:sort_filter]})) %></li> <li

Yii ClientSide Validation on Render Partial not Working

阅读更多关于 Yii ClientSide Validation on Render Partial not Working

问题 I have a Yii form which calls a render partial from another model (team has_many team_members). I want to call via ajax a partial view to add members in team/_form. All works (call, show, save) except for ajax validations (server and client side). If i submit form, member's model isn't validating, even in client side, it's not validating the required fields. Any clue? //_form <?php $form=$this->beginWidget('CActiveForm', array( 'id'=>'team-form', 'enableAjaxValidation'=>true,

Html.RenderPartial call from masterpage

阅读更多关于 Html.RenderPartial call from masterpage

Here is a scenario: Let's say I have site with two controllers responsible for displaying different type of content - Pages and Articles. I need to embed Partial View into my masterpage that will list pages and articles filtered with some criteria, and be displayed on each page. I cannot set Model on my masterpage (am I right?). How do I solve this task using Html.RenderPartial? [EDIT] Yes, I'd probably create separate partial views for listing articles and pages, but still, there is a barrier that I cannot and shouldn't set model on masterpage. I need somehow to say "here are the pages" as an

阅读更多关于 render a partial from jquery and haml

The functionality I plan on doing is to insert some form elements depending on a number chosen from a select tag. I have a select tag called for number_of_passengers, and i plan to dynamically append new passenger fields for the number chosen. Say I select 2 from number_of_passengers, then 2 forms should appear in a fieldset. these forms contain name, age weight etc. I tried following this: call a rails function from jquery? and just converted it to haml-speak but I get errors whenever I use the :javascript tag. Also I don't think I can "escape" the javascript tag once I am in it :javascript $

ASP.NET MVC Razor Sections and Partials

阅读更多关于 ASP.NET MVC Razor Sections and Partials

I'm relatively new to ASP.NET MVC and Razor. We've been modifying and developing based on existing code. Thus, there is a lot of duplication (ugh!). So I started looking at Partial pages and learning about Sections. I followed these tutorials but I'm still a bit confused. ASP.NET MVC 3: Layouts and Sections with Razor Various ways of using Shared Layout in ASP.NET MVC Optional Razor Sections with Default Content Razor, Nested Layouts and Redefined Sections I've been able to create Sections with Partials in them. My question is: While one section will always change upon user selection, I may

Html.Partial vs Html.RenderPartial & Html.Action vs Html.RenderAction. can any one please describe the difference

阅读更多关于 Html.Partial vs Html.RenderPartial & Html.Action vs Html.RenderAction. can any one please describe the difference

In ASP.NET MVC, what is the difference between: Html.Partial and Html.RenderPartial Html.Action and Html.RenderAction Html.Action invokes the controller's action, which means it instantiates the controller entity, calls an action method, which builds a model an returns a view result. Html.Partial uses already created model (or can be called without model at all) to render a specified view. When to use one over the other? If you already have a model and just want to have a reusable view, opt to Html.Partial . If you see that some piece deserves its own model and action, maybe it makes sense to
