I'm trying to setup a iPad app to work offline. I was able to successfully get it to work but I was told to put the app in multiple sub directories. When I did this and update the cache manifest file to the new destinations of all the files I kept getting an error that the site wouldn't work because it wasn't connected to the internet. I tried multiple paths and looked up different ideas but have come up empty handed. Is their a way to get offline mode working with a site inside sub directories?
Thanks.
This shouldn't make a difference. Make sure all urls in the manifest are relative and always end the manifest with:
NETWORK:
*
Furthermore make sure you don't forget to add any images, libraries etc. from the cached url's to the manifest. Sometimes even caps can make a difference. OPen the console of the developer tools in Chrome to see what's being cached and what breaks loading the appcache.
Also make sure there are no iframes (ie. like-buttons) on the homepage(page that includes the manifest attribute in the html-tag) which is always cached.
Little trick:
If you want to fallback you're homepage place the manifest attribute in an invisible iframe on the homepage of your app.
That way you have total control over what's cached and what not.

I have an electron app, and when I make it, it packages and compiles everything.
Sounds like it works perfectly right?
Well, problem is I want one of the folders to not be compiled, but still be accessible by my static files, so the users can add or remove content from the folders.
I've tried making it in a seperate folder, but then it can't find the files even when it's placed in the correct relative path.
Overall, I want my app to exist next to a folder and my <script src="./folder/script.js"></script> to actually be able to access it.
I'm new to basically anything node or electron so i'm probably making some dumb mistake.
Thanks in advance.
Having your user touching files close to your Electron application may be fraught with danger. If they accidently overwrite an important file or accidently delete an important file then your application may stop working and require the user to perform a re-install.
Instead, have any default files the user may need to "touch" packaged up with your application and then upon your applications first run, copy these files (and any necessary folder structure) over to the users home, desktop, documents, downloads or even userData directory.
That way, your application will always know where to find them and the directory is a directory your user will already be comfortable adding files to and removing files from.
You can always let the use choose where these files are stored as a settings option which persists in an application setting file, using something similar to path.join(app.getPath('userData'), 'settings.json');
See Electron's app.getPath(name) for more information.
When I open the Umbraco (7.6.3) backoffice, I'm unable to view or make changes to templates. It seems like other functionality is unaffected, and I can create & edit specific pages. However, attempting to open the templates themselves just leads to a white screen. This problem exists across browsers:
Other screens render just fine:
What gives?
Checking the console when attempting to load gives an interesting error:
Error: Argument 'Umbraco.Editors.Templates.EditController' is not a function, got undefined...
Resolution:
The issue seemed to be caused by outdated files in the Umbraco folder. Copying most directories over from packages\UmbracoCms.7.6.3\UmbracoFiles\umbraco\ seems to have done the trick.
Looking at the changelog, it seems like the JS folder was the most influential in getting this fixed.
Are you sure that you're on 7.6.3? The UI appears to be pre-7.6 (I can tell because the colours haven't been updated).
If you have just upgraded, it's possible that your browser has cached the JS which is used - hard refresh your browser to see if the UI updates.
Umbraco also uses a dependency service to compile all of the used JS/CSS files together into one large one. This service will not be used if your website is in debug mode. Either:
Turn debug mode on in the Web.config
Delete any files in the \App_Data\ClientDependency\ folder as this is where the cached compiled files are kept (these will be regenerated)
My first thought would be file permissions.
Have you run the health check for permissions in the developer section? Need to make sure that your application pool user has write permissions on the Views folder.
Using MVC 4 I downloaded Blackcity Backload from nuget, I am trying to save the uploaded images to a file that is within my project. Everything works great and it shows that the image uploaded, except for the fact that after you upload a new image, and refresh the page the image does not appear in the list of returned images even though it was saved. Also if you delete a file it comes off the list at first but again if you refresh the page it is back. If you rebuild the application then everything appears as it should and the images in the backload file list are all listed correctly and they match what is in the actual file.
I thought it may be a server cache issue but I did all i can to prevent the server from caching and still same problem.
I think it may have to do with the fact that Backloader is dynamically creating folders to put the images in and they are not included in the project even though they are in the file structure. So since they are not part of the project they are not being returned in the get request. Its not until you rebuild that they are recognized as part of the project.
Is there a way to dynamically include new files in the project without rebuilding?
Please help. This is killing me.
Ok this is solved. Had to remove filters.Add(new AuthorizeAttribute()) from my global filters and then add [Authorize] to each controller and it worked.
I have an Umbraco (v6.1.6) website, hosted on Azure Hosted (Website & DB).
Recently the client reported, that some images have disappeared from the website!
Looking at the CMS back office, the content nodes are referencing media items, but 'some' of those items are no longer present in the media section! The media files are however present on the web server in the /media folder as expected!
Now, this should be running as a single instance site, but looks like the site was run in with multiple(3) instances for a while, such as when the missing images were loaded.
[All the unaffected media has lower id’s (<10000) while the missing items in the media section have higher ids (20000’s or 50000’s)]
The site is now back to running one instance.
Q. Is there a way I can re-generate the items in the Umbraco Media section, based on the media actually present in the /Media folder?
What you need to do depends a lot on the state of your site and what has been going on while it was running in 3 instances... and what you want the outcome to be!
Metadata for media in umbraco is stored in the database and the actual files are stored on disk. If your site has been running in 3 instances using the same database but different file locations on disk, you should actually be seeing that the media items exist in the database even though the files might be scattered in the 3 instances on the file system.
It however sounds like you're saying that the files all do exist on disk, but the media items not all exist in the database. Can you confirm this (as it sounds really strange unless you have been running 3 different databases also).
All in all, everything here sounds really strange since running 3 instances should also require you to have had this running and accessed by the editors uploading the files, using 3 different hostnames?
No matter what I don't think theres a simple solution to your problem. There's no way to have umbraco "reindex" the media folder based on the files there. What I have done for broken media libraries (usually self inflicted breakage, that is) is to load up all existing media items in memory and then loop through the file system to see what is missing from the library and recreate those media items and upload the files to them. Do remember to log which files you are recreating as media items so you can do a file system delete of the orphaned files after they have been processed.
If you can shed a bit more light on the issue, I will see if I can come up with a better solution for you.
In my Grails app I have various images:
/web-app/images/competition/foo bar.png
/web-app/images/competition/foo bar2.png
/web-app/images/competition/foo bar3.png
The name of the image to be displayed is stored in the model that's passed to the GSP. I'm trying to create a link to this using the <r:img> tag provided by the resources plugin. So far I've tried:
<r:img file="competition/${imageName}.png"/>
<r:img file="competition/${imageName.encodeAsHTML()}.png"/>
<r:img file="competition/${imageName.encodeAsURL()}.png"/>
But none of these seem to work. I realise renaming the file would make my life a lot simpler, but sadly this is not possible.
Add the below entry in ApplicationResources.groovy as.
modules = {
images {
resource url:'images/competition/foo%20bar.png'
}
}
and access it in view as
<r:img uri="/images/competition/foo bar.png"/>
or
<r:img file="competition/foo bar.png"/>
You should be able to access the resource.
Note:-
Accessing the resource as
<r:img file="competition/foo%20bar.png"/>
did not work for me. Apparently, I made sure I am not reading from browser cache so I followed the below steps:
Tested in Chrome Incognito Mode.
Cleared browser cache every time.
Tested in Firefox and IE.
Cleaned and compiled the project to replicate the issue every time, in case browser was served from the cache.
