There are two web-apps:

• an app for desktop browser;
• an app for mobile browser;

Ahead of them there is nginx. I have a trouble to configure nginx's reverse proxy depending on a browser type (desktop/mobile).

There is an example of a config below:

I use php and laravel. I have a column named MsgBody. In this column, there is an array as follows. I want to get the value of "conversationDesc" from this array. What should I do in the Controller and blade part for this?

I have a class of Form and Student. A student may have 0 or many forms. I set the relation between them as OneToMany. Now, I need to fetch the forms that are owned by a specific student. I have two questions at that point. How should I fetch those forms in the URL? Let's say I want to fetch the forms of the student with id=7.

Option 1:

I am using Flutter for mobile app development. I need to make a POST request to a PHP file in order to save data in my MySQL server. However, I check the request status code it seems OK(200).

I have try to send request to external API in order to perform PATCH method. I have a view defined as below: def dome_view(request, id): ......

I need id in order to pass it to form action and make necessary update on other endpoint which is external.My url pattern is like that path('dome2/int:id/', views.dome_view, name='dome_view'),

When I put id to my form action like below, i got an error "Reverse for 'dome_view' with no arguments not found. "

form action="{% url 'dome_view' id %}"

But when i put the exact id that i want to update, then PATCH method succeded. For example: form action="{% url 'dome_view' 5 %}" method="post">

How can i achieve to successfully send PATCH request without specifiying exact id every time to form action? I just want to do it like <form action="{% url 'dome_view' id %}" method="post"

What am i missing?

[UPDATED] I'm working on a nonlinear ODEs system optimization and fitting it to experimental data. I have a system of 5 model ODEs which must be optimized by 17 parameters. My approach is to calculate the differences between solved ODEs and experimental data - function Differences, then use leastsq solver to minimize diferences and find the optimal parameters, as below code:

I am trying to make a program in python that counts the characters in a text. It works when I input text without new lines like Hello world! and says there are 12 characters but then when I input something like

i'm pretty beginner in the JavaScript and I really need help to convert an array to an array object. There are many examples here in stackOverflow, but I need some modidfication during this process, which is why I couldn't do anything
