partial

问题 I am using MVC 3 with the Razor view engine. I want to set some values in the ViewBag inside a Partial View and want retrieve those values in my _Layout.cshtml. For example, when you setup a default ASP.NET MVC 3 project you get a _Layout.cshtml file in the "/Views/Shared" folder. In that _Layout.cshtml the Page Title is set like this: <title>@ViewBag.PageTitle</title> Then in "/Views/Home/About.cshtml" view the contents of the ViewBag are modified: @{ ViewBag.Title = "About Us"; } This works

问题 Ryan Bates' nifty_scaffolding, for example, does this edit.html.erb <%= render :partial => 'form' %> new.html.erb <%= render :partial => 'form' %> _form.html.erb <%= form_for @some_object_defined_in_action %> That hidden state makes me feel uncomfortable, so I usually like to do this edit.html.erb <%= render :partial => 'form', :locals => { :object => @my_object } %> _form.html.erb <%= form_for object %> So which is better: a) having partials access instance variables or b) passing a partial

问题 Say I have such an array: arr = ['footballs_jumba_10', 'footballs_jumba_11', 'footballs_jumba_12', 'footballs_jumba_14', 'alpha_romeo_11', 'alpha_romeo_12', 'alpha_juliet_10', 'alpha_juliet_11'] If I wanted to return duplicates, (assuming any of these strings in the array were exactly identical, I would just return arr.detect{ |a| arr.count(a) > 1 } but, what if I wanted to get only duplicates of the first 10 characters of each element of the array, without knowing the variations beforehand?

问题 I have a CSV file which I want to parse in Java with OpenCSV's csvreader. To do so I have created a bean object to which the information is mapped. Mine is a bit long so here's an example I got from a tutorial : package net.viralpatel.java; public class Country { private String countryName; private String capital; public String getCountryName() { return countryName; } public void setCountryName(String countryName) { this.countryName = countryName; } public String getCapital() { return capital

问题 render @some_object will render Rails.root/app/views/some_objects/_some_object.html.erb Now I want to handle which partial will be rendered depends on its data_type field. For example: class SomeObject < AR::Base # some magick method wich I need to rewrite def partial_name case data_type when "String" "string_template" when "Text" "text_template" else "blank_template" end end end I know there is model_name , i18n_key and some others, which are returnes model name, but which one is used in my

问题 I want the following on my form: Degree is polymorphic partial with has_many relation to profile. This partial is called by main form - profile. By pressing 'Add a Qualification' user can add as many degrees. I've been able to attach only one degree to profile which is the last one others are all ignored. I even know why it's happening because link_to is not able to pass profile instance. so I have to create new profile in degrees_controller as you can see in my code here. Can final profile

问题 I'm trying to extract new revisions of Chromium.app from their snapshots, and I can download the file fine, but when it comes to extracting it, ZipFile either extracts the chrome-mac folder within as a file, says that directories don't exist, etc. I am very new to python, so these errors make little sense to me. Here is what I have so far. import urllib2 response = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/LATEST') latestRev = response.read() print

问题 I have tried to include a partial into a modal something similar to this Rails Admin when you click on "create language". Now as I have not really found out how the code works there, I tried to do a mix between this Rails - AJAX a Modal Dialog? and something own. The thing is, the partial gets rendered now into the modal. But when I hit "save", the validation will go back to the "normal" create-new view and not show the validation errors directly within the modal. How can I show the
