kandi X-RAY | vurl Summary
Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Control pattern. This pattern splits the view (also called the presentation) into "dumb" templates that are primarily responsible for inserting pre-built data in between HTML tags. The model contains the "smart" domain objects (such as Account, Product, Person, Post) that holds all the business logic and knows how to persist themselves to a database. The controller handles the incoming requests (such as Save New Account, Update Product, Show Post) by manipulating the model and directing data to the view. In Rails, the model is handled by what’s called an object-relational mapping layer entitled Active Record. This layer allows you to present the data from database rows as objects and embellish these data objects with business logic methods. You can read more about Active Record in link:files/vendor/rails/activerecord/README.html. The controller and view are handled by the Action Pack, which handles both layers by its two parts: Action View and Action Controller. These two layers are bundled in a single package due to their heavy interdependence. This is unlike the relationship between the Active Record and Action Pack that is much more separate. Each of these packages can be used independently outside of Rails. You can read more about Action Pack in link:files/vendor/rails/actionpack/README.html.

ANSWER
Answered 2021-Apr-19 at 05:04You are right, you have made a mistake in coursecontent = Videos.objects.filter(subject=vds)
Subject must either be the pk or an instance of subject but you're giving it another video instance. What you want is

I am getting an error on logging out from an application via Chrome browser only.
Chrome browser version 86.0
Blocked alert('Uncaught NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://host-name/web/base/logout?id=40dee37f-cf1d-40f9-b01d-2a414d446a77&tenant=ABC&isFrameMode=true&_dc=1602665141328': Synchronous XHR in page dismissal.

...ANSWER
Answered 2020-Oct-16 at 02:42The problem is not the ajax call. The problem is the call is, based on the error your are getting, happening during an event that is no longer allowed, beforeunload, unload, pagehide, visibilitychange... etc
Here are some alternate ways to return data to the server on logout.
QUESTION
I'm trying to unify all the REST connections created in QlikSense to ServiceNow since I have to create a new connection every time I pull out data from a new table. This will make difficult to manage all my connections in the future and because of that I'm trying to have only one connection that will override specific parameters depending on the required table by using the "WITH CONNECTION" function.
I tried passing the parameters like what's on the code below but after loading the data there's nothing in the table:
...ANSWER
Answered 2020-Jul-31 at 11:04The WITH CONNECTION part can alter some parameters of the connection but not all of them. The http parameters can be changed there like: the url, headers, query parameters and the body. You cant change the rest like: the method (get or post), timeout, http protocol etc. These properties are connection specific and they have to be updated on connection level (when manually editing an connection or updating it via Repository API)
Have a look at the documentation about the WITH CONNECTION keyword
btw the QUERY command will just add a query parameter in the url before sending the request. And thats why you are not getting any data. For example
QUESTION
I've used the below query to fetch data from Oracle 11g and 12c into a dataframe and this works perfectly. However, when I try connecting to on-premise Oracle 9i, this is giving me empty rows though there is data in it.
Any pointers on how to resolve this ?
ANSWER
Answered 2020-Jul-29 at 16:01First thing to check is which JDBC driver do you use.
This is basically the jar ojdbcNN.jar you have on the CLASSPATH, e.g. ojdbc7.jar
Typically you check the Oracle JDBC compatibility matrix in What is the JDBC and RDBMS interoperability matrix or the certification matrix?
This will not help you for Oracle 9, as the oldest version mentioned there (as supported) is 11.2.0.4.
Anyway you may try to use some older version of the JDBC driver, that was distributed with Oracle 9 - possible the classes12.jar. Check older Oracle documentation for details.
QUESTION
I have this piece of code on a site that exports the contents of local storage to a file in JSON format.
For some reason it stopped working. I tested it in multiple browsers but it's all the same...
No errors get displayed, yet it doesn't export either.
The different variables seem fine, yet it just isn't exporting.
To be honest I have no clue how to do this differently so any help would be appreciated.
Thx
...ANSWER
Answered 2020-May-04 at 07:50Here you need to add the download attribute to an anchor tag rather than the clicking button itself. You need to create an anchor tag with display:none and programmatically click it to download the file. Here is an example. Notice the button only used to execute the function and href and download attributes are added to the tag.

...ANSWER
Answered 2020-Apr-24 at 00:14You need to remove the values from the query string that you do not want to duplicate. You can do this by passing the name of that parameter to your function and removing it from the $_GET superglobal and then building a new string.
QUESTION
I have a video tag in which I pass video data i.e src and vtt dynamically, I want to keep vtt for the current video only, and remove all other textTracks.
Right Now on switching the video, all vtt related to previously played videos start playing inside the video tag.
vtt is subtitle
...ANSWER
Answered 2019-Sep-11 at 02:15A bit confusing as your question is for removing vtt cue, but from what you described is removing all other textTracks.
I will explain how to remove all other textTracks.

QUESTION
I have developed a simple Id checking windows forms with C# application to check a set of given Ids valid or not by passing to a webpage using webbrowser control and getting the reply and everything is working fine,its taking 40 - 60 seconds for 20 Ids.one by one.Now i want to speed up the same process using advance threading concept in C# .
Code is working fine i want to improve the performance using threading. any simple suggestion would be great help today
...ANSWER
Answered 2019-Jul-23 at 14:38Here is my suggestion. When the button2 is clicked, a number of worker tasks are started. A reasonable number is 4, but you can try different numbers until you get the best performance. Each worker task will use its own WebBrowser control, and will invoke a subset of the ids. For example the worker task #0 will invoke the ids 4, 8, 12, 16, and 20, the worker task #1 will invoke 1, 5, 9, 13, and 17 etc. Then all worker tasks will be waited to complete, and then the DataGridView can be updated. There is no multithreading involved. Everything happens in the UI thread. No locking or other thread synchronization is required.

I'm trying to build a basic url fetch script in Google Apps Script, but I'm having a problem with the DocumentApp.getUi() function. (note: I know this seems like a duplicate of How do i use DocumentApp.getui() on a new doc, but the answer provided didn't actually answer the question, and it's from 2013)
...ANSWER
Answered 2019-May-01 at 17:09Considering that you are the only one that will be using this, forget about DocumentApp.getUi() and add the URL directly as a literal.
Assuming that fetch is function defined somewhere else in your project, then
