QUESTION
I have a Wordpress website page where I want to enter two values- gender and manufacturer, then display a list which shows which items match the gender and manufacturer selected.
So that the whole page is not refreshed I want to do this with an AJAX request which has to follow a particular route in Wordpress which has got me completely lost. At the moment I am having trouble even passing my two variables from the HTML page through to the JS and PHP.

QUESTION
Greeting, in general the problem is this, I created a web application using React JS, like a database using Firesbase Firestore. Everything worked fine until it was time to update the security rules (they were temporary, well, and time was up). It demanded to immediately change the rules, otherwise the base will stop responding after the expiration of the term. At first, I just extended the temporary rules, but it only worked once, after that all such attempts were in vain. After reading the documentation on writing security rules and looking at a couple of tutorials, I decided to write simple rules allow read: if true; allow write: if false;
. In the project, the user does not interact with the base in any way, the text simply comes from the base and everything is essentially, so these rules are more than enough. I also additionally checked these rules on the emulator and everything went well. I saved the rules, but the application did not rise, I tried other options, to the extent that I simply put true
everywhere and made the base completely open, but to no avail. I have already tried everything and crawled everything, but I still could not find a solution.
My app code:

Answered 2021-Jun-08 at 12:01Posting this as a Community Wiki as it's based on the comments of @samthecodingman and @spectrum_10101.
The error is being generated by either testEng/test
or testUa/test
not actually existing, so their data will be set as undefined. So it's likely that the root cause of this issue is located somewhere else in your app.

QUESTION
I'm junior currently learning gradle and groovy. this is what the book I'm reading says during wrtten build.gradle
...ANSWER
Answered 2021-Jun-01 at 05:23Based on the documentation, using the apply
method is a traditional
and legacy
mechanism to apply a plugin, and they suggest not use this method anymore. So, the suggested mechanism is using the plugins
block.
Applying plugins with the plugins DSL:
There are some key differences between the plugins {} block mechanism and the “traditional” apply() method mechanism. There are also some constraints, some of which are temporary limitations while the mechanism is still being developed and some are inherent to the new approach.
With the introduction of the plugins DSL, users should have little reason to use the legacy method of applying plugins.

QUESTION
I am trying to parse only part of provided JSON. I am using Newtonsoft.Json.Schema nuget. For the next example, I want to deserialize only name and age properties.
...ANSWER
Answered 2021-May-24 at 13:31I don't think there is any built-in method for your usecase, because the additionalProperties
is meant to either forbid/allow additional properties. But once they are allowed in the schema, they are also deserialized. It doesn't make much sense to me to allow additional properties in the schema, but then don't allow them to show up in the data. Maybe you can explain your usecase?
The simplest would probably be to deserialize to a class instead of JObject
. And in that class only define the properties you would like to see
