forego | Foreman in Go

I discovered one problem while creating my project. If someone refer to the issue I will be grateful. In my project I use a layered model. The repository layer (data access layer) that communicates with the database (DB) and the service layer (business logic layer) in which services and objects are implemented (data transfer object).

As a result, there is a problem with the dbSet.Update method. When object (obj) comes into Update method as parameter, during the method call of the _db.Entry(dbSet.Local.FirstOrDefault(i => i.Id == obj.Id) ?? obj).State = EntityState.Modified or _db.Update(dbSet.Local.FirstOrDefault(i => i.Id == obj.Id) ?? obj) in the case of the first user's update (like from "view.xaml") obj is update and changes saving in the database (because dbSet.Local.FirstOrDefault(i => i.Id == obj.Id) returns null and obviously my obj gets into the _db.Update method). In case of a repeated user's update (in the "view.xaml" view) object obj -- when it gets into the _db.Update(dbSet.Local.FirstOrDefault(i => i.Id == obj.Id) ?? obj) method, it isn't take account, as the data context already tracks it and in the _db.Update method gets an object from dbSet.Local.FirstOrDefault(i => i.Id == obj.Id). Everything would be fine if this object in dbSet.Local was updated according to the type that comes from the user. However, this is not the case, it is tracked but not changed when the user edits its properties. It is not tracked properly rather due to the fact that I use services and, accordingly, data transfer object entities.

In view of the foregoing, I have a question. How to make to update entity (by a new modified object) that are tracked, or how to manually assign the necessary object in dbSet.Local to replace the one stored there? or how to make Microsoft.EntityFrameworkCore.ChangeTracking not track changes to my objects in any way?

In order to make changes not tracked I used the QueryTrackingBehavior.NoTracking parameter for the DbContextOptionsBuilder entity, but this only helps on the first load, and tracking is still used when the data is updated further. I also used the dbSet.Local.Clear() methods, but this is a bad idea, as data updating due to the deletion of the previous data from the database (like delete 20 rows from table and add one updated).

I am trying to combine multiple partial legends (i.e. for two different features of one plot) legends into one box. My real-life data is a plot made with geom_sf() with fill colors for polygons and a specific border highlighted made with geom_sf()with a line. Since the line is only one feature, it makes no sense to do a separate legend.

I'm trying to set a reverse proxy using jwilder/nginx-proxy container.

I have a small Express app:

I have a bunch of LLVM IR / BC files that, at the moment, I am compiling to native code with LTO using clang:

I have a rails app with sendgrid API setup and I can send transactional emails just fine. Now I want to be able to send newsletters but I'm a bit confused about the flow and how to keep track of which users want to unsubscribe from the newsletter.

The way I was considering doing this is when a use signsup to automatically send a request to the SendGrid API and add them to the contacts list, and if they want to unsubscribe from the newsletter or transactional emails from my app's settings page I can save this info in my app's DB but also send a request to sendgrid's unsubscribe list to change the value there too. Now I can create a newsletter in sendgrid and send it out from there without having to do anything within my app. One caveat to this approach would be if the users clicks the unsubscribe button via the newsletter and the value gets changed in sendgrid but the change won't be reflected in my app - To work around this would it be better to create a cron job that periodically checks sendgrid for any changes and then save them to my DB, or should the unsubscribe page be part of my app, and when they select unsubscribe I save it to my DB and then push the changes to sendgrid? If i do this approach, would I require users to sign in if they want to make these changes?

An alternative approach would be to forego creating any contact lists in sendgrid and just create the email in sendgrid and sent it out using a rake tasks to trigger the sending?

Apologies if this is a very basic question, but this is my first time trying to setup newsletters etc and can't seem to find anything online about the best strategy to take in order to do this - I hope this question makes sense.

Here is the background information for this question: I have a inventory which contains the information about remote nodes. I also have a template file. I'm trying to render this template to remote end and the rendered result should only contain the information about its target. For example, when I render my template to ops1, the result should only contain the information which defined in my Inventory file（[ceph_osd] - ops1 - rules）

This is my Inventory file:

I have a list of start and stop coordinates of ranges and would like to fill a pandas df according to their being present in a range.

The numbers of rows are predetermined and filled with '0'. If for example a range is 1,3 for a column then rows (index) 1-3 would be filled with '1'.

I have the following "random" Dataframe and want to apply a subset based on logical operators and then want to extract the foregoing rows:

I'm trying to style a custom login page for private pages in Wagtail, as per the docs.

If I follow the recommended method (for my app website) and place my template in 'website/password_required.html' (or website/templates/password_required.html), Wagtail does not pick up the new template. Instead it loads wagtailcore/login.html. I have tried several different locations for the customized template (including website/templates/website/. No location seems to catch it.

However, if I forego PASSWORD_REQUIRED_TEMPLATE and just directly override login.html with website/templates/wagtailcore/login.html, then it works. But I'd rather do this the right way than the way that just works.

I'm pretty sure that this is one of those situations where I've missed something small but crucial. I just can't figure out what it is.
