I trying to load feeds from my blog but this is resulting in the error in the title mentioned.
The error message:
NoMethodError (undefined method `entries' for 0:Fixnum):
app/controllers/pages_controller.rb:6:in `home'
This is how I'm doing:
I created a file in the libfolder called blog_feeds.rb, that contains only the following:
module BlogFeeds
require 'feedzirra'
def load_feeds
feeds = Feedzirra::Feed.fetch_and_parse('http://blog.shigotodoko.com/feed')
end
end
And the line #6 for the error is:
#feeds = load_feeds.entries
Note that this error only occurs sometimes, not always.
So, any idea about what's going wrong here?
Thank you!
When fetching a feed, Feedzirra will return the HTTP status code instead of an object containing the feed entries, if the HTTP fetch results in an error (i.e. not a 200 or 3XX).
In order to handle this condition gracefully, check the type of the object you get back from fetch_and_parse by wrapping it in something like:
unless feeds.is_a?(Fixnum)
# work with the feeds object
else
# handle the error condition, retry, etc.
end
You should also be able to see these failures by fetching the feed in a browser repeatedly, if it's frequent enough.
Well, seems that was something wrong with my code before.
I was trying to randomize some posts and using something like this on the view:
#feeds.shuffle!.first(5)
In order to get the first 5 random posts.
And to fix it, I just replaced the shuffle! method for the shufflemethod.
Now, everything is working fine!

I get this error in my log files every time a cache file doesn't exist it seems. On the first page load, I always get this error
[message] => filemtime(): stat failed for [...]/runtime/cache/my/myapp03eab921185f7b68bbca50d8debc0dda.bin
[file] => [...]/vendor/yiisoft/yii2/caching/FileCache.php
[line] => 113
It doesn't happen anymore on next page loads but that one time is really annoying since the slack bot watcher is spamming our channel with this useless warning. Is there a way to avoid that, or is it a permission problem?
The "runtime", "cache" and "my" folders all have 775.
Update
Turns out the issue is that I'm using error_get_last() that is also getting warning-level errors. So it's a different issue entirely, not Yii-related
Make sure that you don't have enabled scream in your php.ini. Warnings from this filemtime() call should be suppressed by # operator, but scream setting can override this operator and generate warning anyway.
if (#filemtime($cacheFile) > time()) {
// ...
}
You must be getting this in PHP 7.1. try to run this with PHP 5.5 and see if you are getting the same error.
To reproduce you need to delete all files from runtime/cache directory
Then start app again(reload page) and look into runtime/cache. It is empty
Yii2 doesn't make cache again
Got same issue in Yii. The error was on the same string (FileCache.php:113)
if (#filemtime($cacheFile) > time()) {...
In my case reason was that my custom php error handler (heir
of the class yii\base\ErrorHandler) didn't check if
error type need to be handled according error_reporting().
Custom handlers allways gets every error, even muted by Error Control operator (#)
https://www.php.net/manual/en/function.set-error-handler.php
error_reporting() settings will have no effect and your error handler will be called regardless
I'm having an issue where I've got a button that's action is to 'submit page' upon being clicked. The code then executes a PL SQL statement:
IF :REQUEST = 'btn_create_company' THEN
INSERT INTO COMPANIES (company_name) VALUES(:COMPANY_NAME);
However, when the code comes to execute, whilst it is adding the entry to the database, I'm getting this error on the client which is preventing the page from redirecting after processing:
Error: SyntaxError: Unexpected end of JSON input
I don't understand why this is happening as I'm confident there's nothing wrong with the above statement.
Ok, so I get this problem too, It's when I submit the page but instead of reload the whole page, I'm running a process and stay there.
The process itself works well, however I get the error message, just like you.
So I don't get the a solution, but found a workaround by adding this to the end of my process:
apex_json.open_object;
apex_json.write('success', true);
apex_json.close_object;
You are missing the page number on :COMPANY_NAME. It should be something like :P1_COMPANY_NAME
I was encountering a similar error when operating the last page in a chained dialog (aka "wizard") I had created.
The cause of my issue was that I had created a branch on the "After Submit" with the Behaviour/Type attribute set to "PL/SQL Procedure" and then had the code I wanted to be executed within the PL/SQL code attribute. When the "Finish" button was clicked, I was seeing the same error.
My resolution was to delete the branch and instead to use Create Process, with the Identification/Type set to "PL/SQL Code" and then placing the code I wanted to be executed within the "Source/PL/SQL Code" attribute.
I can't figure out what I'm always getting 400. This is my model:
class G2
extend Garb::Model
metrics :pageviews
end
and this is my call:
G2.results(profile, :filters => {:pageviews.gte=>3})
and I get this:
Garb::BadRequestError: [400] Invalid Value : https://www.googleapis.com/analytics/v3/data/ga?ids=ga:XXXXXXXX&start-date=2013-01-07&end-date=2013-02-06&metrics=ga:pageviews&filters=ga:pageviews%3E%3D3
If I don't include the :filters symbol, then the request will be successful. I tested this query using the GA Query Tool and it works.
Any thing I have missed?
It turns out that this is a bug caused by a recent check-in to garb. The author (sija) has reverted the change and this issue no longer reproduces: https://github.com/Sija/garb/issues/17
There's got to be an easy way to do this, but I cannot find an answer...
When some creates or updates a WorkRequest in my app, I do other processing, including creating a Workflow object. I do some checking to make sure, for example, there isn't more than one Workflow already created for this WorkRequest. If there is, I want the update/create to fail with an error message. I just can't see how to do this. I tried returing false from my before_update callback method, but this did not work.
Do I raise an error and rescue it in my controller? What is the right way to do this in Rails 3?
Any help would be much appreciated.
This is why you have validations. You can implement an own validation like this:
class ...
validate :my_validation
def my_validation
if workflows > 1
errors.add(:workflow, "cannot be more than one" )
end
end
end
I'm trying to use SPWeb.GetListItem() to get an item by a known URL (MSDN).
So basically I'm doing the following:
using (SPSite spSite = SPContext.Current.Site)
{
using (SPWeb spWeb = spSite.RootWeb)
{
SPListItem spListItem = spWeb.GetListItem
("/sites/testSite/Lists/testList/Folder/Subfolder");
}
}
in case you are wondering, I'm trying to get the folder "Subfolder" to do stuff with it.
The problem is that the first time I call this, I get a COMExpeption:
Cannot complete this action.
Please try
again.<nativehr>0x80004005</nativehr><nativestack></nativestack>
Description: An unhandled exception
occurred during the execution of the
current web request. Please review the
stack trace for more information about
the error and where it originated in
the code.
Exception Details:
System.Runtime.InteropServices.COMException:
Cannot complete this action.
There are some reports about the COMException happening because you need to use the full relative site URL, so instead of /Lists/testList/Folder/SubFolder, you need to use /sites/testSite/Lists/... - I'm doing just that. I also tried using the absolute URL (http://sharepoint/sites/...). The problem remains: I get the COMException when trying to get the spListItem for the first time.
When I try to run the code again after the Exception, the SPListItem is received just fine. Also all subsequent calls work - only the first one fails.
AmI doing some initializing wrong or something like that?
Perhaps try SPWeb.GetFolder() instead... but again it depends on what exactly you want to do with the Folder. Seems strange though that you're using a method used for getting list items on a Folder.
http://msdn.microsoft.com/en-us/library/ms461547.aspx
Try to instantiate the web where the list item is located - _uiserWeb.
I tryed Site.RootWeb.GetListItem(item_url) - it gave me null first time after code redeployment and was fine second time.
_item = _userWeb.GetListItem(item_url)
