| Issue trying to programmatically post messages to a private Facebook group using Graph API Posted: 08 May 2022 09:54 AM PDT I am trying to programmatically post messages to a private Facebook group. I plan to write the code to do this in Python. I would like to run the code from my laptop. I have seen multiple articles demonstrating how to write this code. I don't need help with that. I am an Admin user in the private FB group. The issue I have is the techniques described all depend on creating an app. This seems like overkill to me. I don't need a general-purpose app. I'd prefer not to go through the burden of getting an app approved. Thus far, the only way I have seen to enable the required permissions to write messages to a group is by creating an app and adding that app to a group. Is there a simpler way, that does not require writing an app, that then must be approved, when I don't need an approved general purpose app? Thus far, I have not been able to post this question to the Facebook community. The webpage is throwing a cryptic error when I try to post. |
| Expand embedded list of dictionnaries in a DataFrame as new columns of the DataFrame Posted: 08 May 2022 09:54 AM PDT I have a Pandas DataFrame looking like: df0 Out[414]: 0 1 2 0 12 None [{'dst': '925', 'object': 'Lok. Cert... 1 13 wXB [{'dst': '987', 'object': 'Lok. Fral...
Each of the list in the column 2 is having the exact same keys (dst, object and admin): [ {'dst': '925', 'object': 'Lok. Certification', 'admin': 'valid'}, {'dst': '935', 'object': 'Lok. Administration', 'admin': 'true'}, {'dst': '944', 'object': 'Lok. Customer', 'admin': 'false'}, ... ]
I wish I could expand the df0 DataFrame to look like this: columns = ['id', 'name', 'dst', 'object', 'admin'] df_wanted Out[416]: id name dst object admin 12 None 925 'Lok. Certification' 'valid' 12 None 935 'Lok. Administration' 'true' 12 None 944 'Lok. Customer' 'false' 12 None 945 'Lok. Customer' 'false' 12 None 955 'Lok. Certification-C' 'invalid' 12 None 956 'Lok. Certification' 'valid' 13 wXB 987 'Lok. Fral_heater' 'valid' 13 wXB 986 'Lok. Fral_cond.' 'valid' ...
Notice that the two first columns, id and name, are replicated along the rows to fit the number of elements within their list. (The dst column must be cast to an int using .astype(int) at the end.) How could I achieve that? Info: Python 3.10.4 pd.__version__ '1.4.2'

| Git branch locally and remotely can any one please tell me this is my first question? Posted: 08 May 2022 09:54 AM PDT The best way (actually the only way*) to simulate an actual click event using only CSS (rather than just hovering on an element or making an element active, where you don't have mouseUp) is to use the checkbox hack. It works by attaching a label to an element via the label's for="" attribute. |

| How to soft delete a selected row in a DataGrid View using a button Posted: 08 May 2022 09:53 AM PDT So I have a DataGridView called MyMovieDataDrid which is connected to a sql server, and I already have my IsDeleted property, and a delete repository which is shown below, by the way my IsDeleted property automatically shows up as a checkbox so if the checkbox is checked it's true if not it's false public bool DeleteMovie(Guid id) { bool isDeleted = false; var movie = _context.Movie.FirstOrDefault(m => m.Id == id); if (movie != null) { movie.IsDeleted = true; _context.SaveChanges(); isDeleted = true; } return isDeleted; }
and here is my Delete button method so when I press it, it runs my logic and soft deletes a row from the DataGridView I've tried multiple solutions like using the selected row event handler to get the selected rows then running the repository method but none have worked so far. private void DeleteButton_Click(object sender, EventArgs e) { Movie movie = new Movie(); if(MovieDataGrid) { _movieRepo.DeleteMovie(movie.Id); } }
and my all of my properties Movie movie = new Movie() { Id = Guid.NewGuid(), IsDeleted = false, MovieNames = MovieNameBox.Text; }
so my question is how do I make my Datagrid know when to run my repository method and I feel like I have to somehow make write some code to where if the IsDeleted property is true it selects the whole row then I run my DeleteMovie Method but no solutions have worked. |

| How to create a chart using MPAndroidChart and getting data from Realtime Firebase Posted: 08 May 2022 09:52 AM PDT am developing an application, where users are able to record and track weight by seeing an chart. I am using Android Studio and coding in Java. The app lets users enter enter weight and the date using date picker dialog. I created a model class that stores the date, time and weight as strings. I had errors when I wanted to store the data as different types. After user enters weight and data and clicks save. The data is saved inside Realtime Firebase. Now in a different activity I want to retrieve these data and show them via a Line chart.

| MongoDB aggregation: concatenation strings in pipeline Posted: 08 May 2022 09:53 AM PDT I am new to MongoDB and faced an issue. In my aggregation pipeline I have such data structure: { "_id": 1, "letter": "b" }, { "_id": 2, "letter": "b" }, { "_id": 3, "letter": "a" } ]
I desire to merge all of these items by letter property in order to have "bba" string in the end(so basically just a concatenation of those letters). I did try reading about mergeObjects which failed because string is not an object as well as reading about other possible approaches. It just looks like I'm missing something here. Is there a possibility to return such result and maybe somebody can help me to understand how? Thanks a lot in advance and have a nice day! |
| Django debugger does not start by VS Code launch.json Posted: 08 May 2022 09:55 AM PDT Until recently my Django projects would debug fine using launch.json file. But it stopped working today and I have no idea about it. Changes made by me in system were: - Clean-Installing Windows
- Installing python in default path just for current user and not all users
Problem Description: - As soon as I click F5 key the debugger starts for some milliseconds and stops automatically without any prompt. As it does not shows any error I tried to log errors by nothing in it. It does not even load terminal to run commands.
The added configuration in launch.json file is as below: { "configurations": [ { "name": "Python: Django", "type": "python", "request": "launch", "program": "${workspaceFolder}\\manage.py", "args": [ "runserver" ], "django": true, "justMyCode": true, "logToFile": true, "console": "integratedTerminal", "cwd": "${workspaceFolder}", "host": "localhost" } ] }
Can someone help to troubleshoot this, I have already tried: - Creating new projects
- Reinstalling Python
- Creating new environment
- Resetting VS Code Sync Settings
- Run other dubug configurations {they are working fine)
- Changing django debug configuration
My current options are: - Research more (Already spent a hours would take more)
- Wait for solution by someone
- Clean Install Windows and all software's (Would be like BhramaAstra)

| Classes with property referencing other classes Posted: 08 May 2022 09:54 AM PDT I'm creating a library, and one part of it requires a structured model. Let's say we have sections, and each section can have subsections (categories). All of them fit this model: class Section: sec_property = "" class Category: sub_property = "" class General: sec_property = "" sub_property = ""
Now, I want to have multiple sections, and each one should have custom categories, or even other sections, which would reference the specific one. Each category inherits from its section, so it has access to the sec_property of the parent. This is what I have right now, but I'm facing some issues with it. class CARS(General): sec_property = "car" CAR1 = None class CAR1(CARS): sub_property = "car1" CARS.CAR1 = CAR1
I want to be able to access CAR1 only through CARS -> CARS.CAR1. The issue right now is, that it acts as a property of the class, not a class itself, meaning the IDE doesn't recognize it properly. Why I want the inheritance, and General class: I want to be able do anyClass.sub_property, and it should either return the empty string or the property itself. I also want to be able to do anyCategory.sec_property, and it should have the property of the parent class (hence the inheritance). I want to avoid duplicating data and other bad practices. The goal # sections.py class MOTOR(PARTS): sub_property = "motor" class PARTS(General): sec_property = "parts" MOTOR = MOTOR class CAR1(CARS): sub_property = "car1" class CARS(General): sec_property = "car" CAR1 = CAR1 PARTS = PARTS
In this example, the CAR1 is an alias to the class itself, not a property, constant or anything. The issue is, that it can't inherit from CARS in this case, which I would very much like to do. I want to be able to access all categories (sub-sections) from the sections themselves, and be able to access the parent attributes (unless they are overridden, where a section would have another section as reference). I also don't want to create duplicates (instead of inheriting the attribute sec_property assign it to each category), as that's not really a great practise. # some other .py import sections sections.CARS.CAR1.sec_property sections.CARS.CAR1.sub_property sections.CARS.PARTS.MOTOR.sec_property sections.CARS.PARTS.MOTOR.sub_property sections.PARTS.MOTOR.sec_property # etc etc
I also don't want to be able to access the categories (CAR1, MOTOR) directly, but I've already figured that one out - create __init__.py and include the stuff I want, and don't include the rest.

| Relying upon circular reference is discouraged and they are prohibited by default in spring boot apolication Posted: 08 May 2022 09:53 AM PDT I am getting below error message when I am running my spring boot application. Description: The dependencies of some of the beans in the application context form a cycle: ┌─────┐ | securityConfiguration (field private com.prity.springbootdemo1.service.UserService com.prity.springbootdemo1.config.SecurityConfiguration.userService) ↑ ↓ | userServiceImpl (field private org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder com.prity.springbootdemo1.service.UserServiceImpl.passwordEncoder) └─────┘ Action: Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

| In Oracle Apex, is there a set of hot keys to activate the Run Command? Posted: 08 May 2022 09:53 AM PDT In Oracle Apex SQL Workshop, is there a set of hot keys to activate the Run Command? I've researched this online and have not found an answer. It seems laborious to have to type out my query and then have to use my mouse to click on Run, when hot keys can help keep my hands on the keyboard. I'm using a Mac and typically through Firefox. Thank you. |
