• Python File Tagging System does not retrieve nested dictionaries in dictionary

  I am building a file tagging system using Python. The idea is simple. Given a directory of files (and files within subdirectories), I want to filter them out using a filter input and tag those files with a word or a phrase.

  If I got the following contents in my current directory:

  data/
     budget.xls
     world_building_budget.txt
  a.txt
  b.exe
  hello_world.dat
  world_builder.spec
  

  and I execute the following command in the shell:

  py -3 tag_tool.py -filter=world -tag="World-Building Tool"
  

  My output will be:

  These files were tagged with "World-Building Tool":
  data/ world_building_budget.txt
  hello_world.dat
  world_builder.spec
  

  My current output isn't exactly like this but basically, I am converting all files and files within subdirectories into a single dictionary like this:

  def fs_tree_to_dict(path_):
      file_token = ''
      for root, dirs, files in os.walk(path_):
          tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
          tree.update({f: file_token for f in files})
          return tree
  

  Right now, my dictionary looks like this: key:''.

  In the following function, I am turning the empty values '' into empty lists (to hold my tags):

  def empty_str_to_list(d):
      for k,v in d.items():
          if v == '':
              d[k] = []
          elif isinstance(v, dict):
              empty_str_to_list(v)
  

  When I run my entire code, this is my output:

  hello_world.dat ['World-Building Tool']
  world_builder.spec ['World-Building Tool']
  

  But it does not see data/world_building_budget.txt. This is the full dictionary:

  {'data': {'world_building_budget.txt': []},  
  'a.txt': [],
  'hello_world.dat': [], 
  'b.exe': [], 
  'world_builder.spec': []}
  
  

  This is my full code:

  import os, argparse
  
  
  def fs_tree_to_dict(path_):
      file_token = ''
      for root, dirs, files in os.walk(path_):
          tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
          tree.update({f: file_token for f in files})
          return tree
  
  
  def empty_str_to_list(d):
      for k, v in d.items():
          if v == '':
              d[k] = []
          elif isinstance(v, dict):
              empty_str_to_list(v)
  
  
  parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
  
  parser.add_argument("--filter", action="store", help="keyword to filter files")
  parser.add_argument("--tag", action="store", help="a tag phrase to attach to a file")
  parser.add_argument("--get_tagged", action="store", help="retrieve files matching an existing tag")
  
  args = parser.parse_args()
  
  filter = args.filter
  tag = args.tag
  get_tagged = args.get_tagged
  current_dir = os.getcwd()
  
  files_dict = fs_tree_to_dict(current_dir)
  empty_str_to_list(files_dict)
  
  for k, v in files_dict.items():
      if filter in k:
          if v == []:
              v.append(tag)
              print(k, v)
  
          elif isinstance(v, dict):
              empty_str_to_list(v)
  
      if get_tagged in v:
          print(k, v)

• Looping the function if the input is not string

  I'm new to python (first of all) I have a homework to do a function about checking if an item exists in a dictionary or not.

  inventory = {"apple" : 50, "orange" : 50, "pineapple" : 70, "strawberry" : 30}
  
  def check_item():
      x = input("Enter the fruit's name: ")
      if not x.isalpha():
          print("Error! You need to type the name of the fruit")
      elif x in inventory:
          print("Fruit found:", x)
          print("Inventory available:", inventory[x],"KG")
      else:
          print("Fruit not found")
  check_item()
  

  I want the function to loop again only if the input written is not string. I've tried to type return Under print("Error! You need to type the name of the fruit") but didn't work. Help
• Upload file from html when block public access is true

  I am using django-s3direct to file upload

  https://github.com/bradleyg/django-s3direct

  Using IAM role setting because I upload the file from the server on ECS container.

  Now I set the blockPublicAccess of S3 false.

  When uploading images from html, there comes error.

  https://s3.ap-northeast-1.amazonaws.com/static-resource-v/images/c64d6e593de44aa5b10dcf1766582547/_origin.jpg?uploads (403 (Forbidden)
  )
  
  initiate error: static-resource-v/line-assets/images/c64d6e593de44aa5b10dcf1766582547/_origin.jpg AWS Code: AccessDenied, Message:Access Deniedstatus:403
  

  OK, it is understandable.

  Browser try to access the for initiation.

  However there is any way to upload file from browser when blockPublicAccess is true??

• Kotlin Coroutines Unit Testing

• Unit testing with get request

  I am trying to create a unit test for one of my api.

  In the frontend, I send it this way...

  params = {
      participants: JSON.stringify(participants),
      section: JSON.stringify(section),
  };
  axios.get('/api/list', params)
  

  while in the controller, it receives the params this way...

  public function list(Request $request)
  {
      $participants = json_decode($request->participants);
      $section = json_decode($request->section);
  
  }
  

  Now, I tried making a unit test out of this. by doing...

  $params = [
      'participants' => ['id', 'name', 'rating'],
      'section' => ['id', 'code'],
  ];
  
  $this->get('/api/list'.http_build_query($params))->assertStatus(200)
  // $this->json('/api/list', $params)->assertStatus(200) // -> also tried this one
  // $this->getJson('/api/list', $params)->assertStatus(200) // -> also tried this one
  // $this->call('GET', '/api/list', $params)->assertStatus(200) // -> also tried this one
  

  But none of them works, it always says TypeError: json_decode(): Argument #1 ($json) must be of type string, array given.

  So, the way I built the url and the params must be all wrong,

  so my question here is that, what's the correct way of building the url so that it provides a correct url string format and the controller will json_decode the params?
• Pytest does not find my tests in Poetry project (VSCode finds)

  I've just created my first Python package using Poetry using the usual poetry new mypackage command. My problem is that pytest does not execute any test when I run it. I'm developing using VSCode and the weird behavior is that VSCode successfully finds and executes my tests.

  Poetry created a subdir called mypackage and another called tests. My test file is called tests/test_mypackage.py.

  VSCode autodiscoverd the tests, and display them in the test tab. The .vscode/settings.json file has this configuration:

  "python.testing.pytestArgs": [
          "tests"
      ],
  

  I've tried the following commands to execute pytest:

  1. With my venv manually activated:
     1. pytest
     2. pytest tests
     3. pytest tests/test_mypackage.py
     4. cd tests;pytest test_mypackage.py
  2. without my venv activated:
     1. poetry run pytest
     2. poetry run pytest tests

  The behavior is always the same: nothing happens, as if pytest couldn't detect anything to run.

  I've been using VSCode to run the tests, but now I want to put the code under Continuous Integration. How do I run pytest to validate my package?
• Multiple flask calls in single pytest having different databases

  So I'm trying to test an endpoint in flask that I need to call multiple times in one test. The issue I am having is that on the second request the objects I placed into the DB using pytest fixture with the scope of function do not appear in the db on that second call. Is this normal / is there a way to change this behavior? Using SqlAlchemy for ORM with a scoped_session. Thanks!
