I'm stuck with a bug at the moment which is puzzling me. I have a
layout containing some HTML and a partial (for the navigation) - there
is nothing else there other than the yield.
If the nav is included as a partial I get nothing returned to the
browser at all (blank page) but everything else appears normal
If I remove the partial the page works fine
If I put the nav code directly in the template it works fine
if I replace the nav code in the partial with a simple string, I get
a blank page again.
Does anyone have any ideas as to what the problem could be, or know how
I might debug it?
Found the issue, the partial was in the layouts folder, instead of the
relevant controller views folder.
However, Rails was throwing a ActionView::MissingTemplate Exception
which was only visible via the debugger which is probably a bug.
First off, check the log file to see if you're getting an error message somewhere. If that doesn't help follow these steps:
Make a copy of your template & partial, linked as the original
Test that they exhibit the problem
Start removing things from them until you have the simplest possible case that still exhibits the problem (your string in the partial test is a step in this direction)
If you don't figure it out in that process, come back and edit your question to include the code for the simplified case
I have had this error on a number of occasions. The problem has always been solved by changing something in the offending template or one of it's partials (in my latest case, I added a blank line into the source between a </div> and a <div>, which was in a partial invoked by the template; changing the template itself had no effect). The really odd thing is that the problem rarely occurs when I actually change a template, but usually when I change something related (e.g. edit an image displayed in the page or the CSS relating to the page). While the problem is often related to a partial, the entire page is blank, not just the portion provided by the partial.
BTW, restarting the web server (in this case Unicorn) does not fix the problem. Running Ruby 1.9.3, Rails 3.1.3. Using SASS and Unicorn.
UPDATE: Just determined that Rails is returning a 304-not modified, based upon the "If-none-match" header sent by my browser (which in turn was based upon the ETAG of the previous page). However, in the meantime, the browser cleared the window. So, presumably, something in what Rails sent caused the browser to clear the window.

I use wicked (1.3.1) (not sure if relevant) for an onboarding flow on my rails 5 app. On the last step of my onboarding process, there is an <a> link that navigates to a user#dashboard page.
This works totally fine in all browsers. For some reason that transition does not work in Capybara (rspec 3.7, rspec-rails 3.7.2, Capybara 2.14). The url changes in the automated browser to the desired route, but the page does not render any content, it retains the old view. Visually its as if someone typed in a url but did not press return, however, the controller method and view are getting touched when i debug them. They appear to return a rendering, but the value is not rendered in the browser
If i throw a sleep in my test after the <a> click, I can manually click on the url bar, press return (to navigate to the correct url) and the page will render then. But not on its own. Anyone experience this before?
I have tried changing the href to a different path to see if it is a problem with the target view/controller - it is not, happens to all of the paths I try. I have also tried different capybara drivers: :selenium, :chrome, :poltergeist. All same result!
Would love to provide more detail but i'm not sure what to show. Its a simple href and i'm not sure what could go wrong.
Cheers
EDIT:
turns out there was an error in the logs. Will update with a solution.
error:
Could not log "render_template.action_view" event. NoMethodError: undefined method `render_views?' for RSpec::ExampleGroups::LayoutsSplash::View:Class ["/Users/mitchellmeyer/.rvm/gems/ruby-2.3.1/gems/rspec-core-3.6.0/lib/rspec/core/example_group.rb:732:in `method_missing'",
The error shown in the logs is a know rspec/rspec-rails 3.6 issue - upgrading will fix that. Beyond that, the fact it works when a URL is submitted manually to the browser but not when clicking on the link indicates the link is probably being interfered with by JS. Most likely that's Turbolinks which you can disable for a given link by adding a data-turbolinks=“false” attribute to the link. If that fixes the behavior (which you state it did) then it's probable you have a JS error in one of your files. Check the developer console in the browser for any errors shown and fix them.
Since you mention Poltergeist, as a driver you tried, in your question it's possible for there to be silent errors that cause JS to fail when using it since it doesn't support anything beyond ES 5.1 so it's not really that suitable for testing modern webapps any more and I would recommend sticking to headless chrome if you need headless testing.
I am running an instance of Umbraco 6.1.x and it has started throwing 404 on published pages.
My page structure is as follows,
Content
Home
About
Course
...
Component
Home
About
Course
Where component holds all resources and modules (HTML sections and stuff) for a page and using a partial view macro I dynamically load all components at runtime for a specific page.
We are facing an issue where we get 404 on every page after a full republish once we hit the HomePage. Before hitting home page they are all fine, but the moment we hit the homepage they are all throwing 404. By overriding the handlers I found out that they are hitting ~/umbraco/RenderMvc!
Any idea what can cause this?
Thanks in advance.
EDIT:
It is actually throwing:
No template exists to render the document at url '/'
considering the aforementioned scenario.
I have proper allowed template setup and property on nodes are showing the correct template associated with the respective items. Not sure why it's losing template info. I can force it to load under correct template using ?altTemplate=templateName.
Some pointers, we have a view in Views/Shared folder (apart from macro partials) tied to a surface controller.
One thing I would like to say is, we are using nested (library.RenderMacroContent with Umbraco markup) in our partial views and I have realized that the whole page throws 404 if there's a page with a link to the broken page which is broken (i.e. page got re-created and on t==e of the components is holding a link to the page with previous id). Suggestions?
did you get to the bottom of this? We're having exactly the same problem at the moment, on the same version of Umbraco.
I've noticed that when it happens, the umbraco.config becomes either corrupt or rolls back to a much, much earlier version, with all sorts of attributes missing. This lead us to believe it was a sync issue between the DB and umbraco.config.
We initially thought we had solved it by deleting App_Data > TEMP > ExamineIndex and recycling the app pool etc. Maybe give this ago, as it fixed it for a while for us, but alas, the demon has reared its ugly head once more. We are still in a full on dev stage though, so the constant changing may be complicating it further for us - perhaps it will be a fix for you.
If you have any more info, or even a fix, it would be greatly appreciated.
Cheers
EDIT:
Ok, I think I've solved this now, but only time will tell. Try emptying your recycle bin & then republish entire site.
I managed to consistently recreate the bug using IIS SEO site analysis. Each time I did this, the log threw up an error 'cannot find node id xyz', turns out that (and other) nodes were in the recycle bin. Upon emptying it the errors stopped. Good luck!
Using Rails 3.2.11 and finding this weird issue.
When the page is rendered, header partial is displayed and even the footer is also displayed in the browser. And the form/content doesn't get rendered and shown blank.
If the page is refreshed then the whole page is displayed.
The weird thing is that it doesn't happen always. It happens rarely which I'm finding kinda lost to debug and its even hard to reproduce.
What might be wrong of how can I debug this weirdness?
Any help would be much appreciated!!!
I just updated active scaffold on my rails app, and now all the links are broken on the site. If I hover over the link in firefox, I can see http://localhost:3000/correct_link; however, when I click the link, I end up at http://localhost:3000/current_link#__1_. When the link is loaded all styling/javascript is messed up. Furthermore, the number after the two underscores increases every time I click another link, but I can never navigate away from http://localhost:3000/current_link__NUM_.
Interestingly, if I type the url that I want into the browser, all is well. There don't seem to be any errors in my logs or in my server console.
I'm not sure how to go about debugging this
Aha! The error was caused by my removing active_scaffold, which introduced some weird behavior from custom javascript that had hooked into it. After active scaffold was removed, the javascript started hijacking the links. Shuffling the javascript around fixed the bug
I am working on a test application based on ASP.NET MVC. I am new to CSS stuff so I am learning that as well.
I have created a master page called "new.master" and created a new css "new.css". I am calling the view from controller as:
return View ("About", "new");
What I am doing is that I am frequently updating the css and master page. So I run the application in debug mode frequently. After sometime I stop seeing the effect of changes in css. When I "view source" in chrome and check the css, it shows an old version.
When I change the name of both master page and css, I start to receive updated views but that works for sometime and then again I stop getting the CSS updates. Have you faced this problem? How can I fix it? (Its terribly annoying!)
Your browser is caching the css. If you force a refresh with F5 that should display any changes.
I think this may be a browser cache issue. In in IE and FF I usually do Ctrl + F5 or Ctrl + Refresh button. Also you can manually clear the cache. For IE you can use the IE Dev Toolbar and for Firefox there is Firebug with both you can clear the cache easily. Not sure about chrome, sorry.

I found another case in which this can happen.
We started our application with just plain links to the CSS files, then switched to using bundling. We updated the old <link href="#Url.Content("~/somePath/someStyle.css")" rel="stylesheet" type="text/css" /> to #Styles.Render("~/Styles/bundles/someStyle").
We also use a few stylesheets which are only needed for some pages, and they have their own bundle. Now, for one of them, we forgot to change the link tag to the #Styles.Render statement.
The result was that this CSS got updated now and then (so we thought everything is OK; the style wasn't missing), but we could not influence when the update happens. When I started making changes to the file, I realized that nothing I do (emptying the cache, rebuilding the project, restarting Cassini) will trigger an update. The browser always got a 304 Not modified.
So, if you have these symptoms, check your links.
Please use Ctrl+F5 to refresh your browser.
F5 may give you the same page even if the content is changed, because it may load the page from cache. But Ctrl - F5 forces a cache refresh, and will guarantee that if the content is changed, you will get the new content.
hope this will help you
Thank you
go to chroom developer panel by right click inspect -> then go to Network tap -> tick the Disable cache checkbox (note: this should always be checked) -> Refresh the page by pressing F5.
this work for me, hope this help others who have this issue! :)
It's very possible that css is being cached in your browser, so simply clearch browser cache, it should help
This happened to me when I had a master view that would load partial views depending on which partial view the user wanted to see, but the answer from this page helped, https://forums.asp.net/t/1763494.aspx?applying+CSS+layouts+to+a+partial+view
CSS must be referenced in the of the Html document. As a
consequence you cannot include them in a partial view...because in
such case the css is included in the Html body. Please plce the style
sheet in head of the page that hosts the partial view.
I would have css links in my partial views and any modifications to the css files would never happen, even if I pressed Ctrl-F5 in the browser. I also tried clearing cache contents in the developer tools. I noticed by viewing the source stylesheets that the css files linked by the partial views were not changing, so the fix for me was to move the css links from the partial view to the main view where these partial views were to be held.
I had something similar happening to me.
Then suddenly noticed the bundle was added to the page:
#Styles.Render("/bundles/classifiedDetailCss")
instead of:
#Styles.Render("~/bundles/classifiedDetailCss")
Note the missing ~ character in the first example.
(The first example only worked after building the project, otherwise it would return a cached version even in debug mode.)
This can help solve this issues in both dev and production.
