• 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)

  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??

• Django (Wagtail) template not recognizing page type for if condition

  On my wagtail blog, I have a simple model that will be the index page listing different articles, defined in my models.py as:

  class ArticleIndex(Page):
      description = models.CharField(max_length=255, blank=True,)
  
      content_panels = Page.content_panels + [FieldPanel("description", classname="full")]
  

  I have some template tags setup to show categories and tags in the sidebar, which should only activate on the index page, not actual article pages. I have this setup thusly:

    {% if article_index %}
  
    {% categories_list %}
  
    {% tags_list %}
  
    {% endif %}
  

  If I remove the if condition, everything displays as I want, so I know it is not an issue with the template tags.

  I don't understand why {% if article_index %} is failing, as that's what the page type is.

  How can I print out what the actual page type is to see where the discrepancy is, or to see why the if condition is failing?
• Wagtail panel for self-referential many to many relationships with a through model

  I am busy making something like a knowledge graph in wagtail.

  CurriculumContentItem is a node on that graph. It has a many-to-many relationship with itself, and the through model has important fields.

  I'm struggling to get this to be usable in the admin page. Please see the inline comments:

  class ContentItemOrder(models.Model):
      post = models.ForeignKey(
          "CurriculumContentItem", on_delete=models.PROTECT, related_name="pre_ordered_content"
      )
      pre = models.ForeignKey(
          "CurriculumContentItem", on_delete=models.PROTECT, related_name="post_ordered_content"
      )
      hard_requirement = models.BooleanField(default=True)
  
  class CurriculumContentItem(Page):
      body = RichTextField(blank=True)
  
      prerequisites = models.ManyToManyField(
          "CurriculumContentItem",
          related_name="unlocks",
          through="ContentItemOrder",
          symmetrical=False,
      )
  
      content_panels = Page.content_panels + [
          # FieldPanel("prerequisites") 
          # FieldPanel just lets me select CurriculumContentItems, but I need to access fields in the through model
  
          # InlinePanel("prerequisites"), 
          # This causes a recursion error
  
          FieldPanel('body', classname="full collapsible"),
      ]
  

  If I wanted to do this in the normal Django admin I would make use of an inlines to specify prerequisites. Something like:

  class ContentItemOrderPostAdmin(admin.TabularInline):
      model = models.ContentItem.prerequisites.through
      fk_name = "post"
  
  class ContentItemOrderPreAdmin(admin.TabularInline):
      model = models.ContentItem.unlocks.through
      fk_name = "pre"
  

  Is there a similar mechanism in Wagtail?

  It looks like I need to create a custom Panel for this.
• Detect Django rest API conditions for accepting data before submitting

  I've an API end point that accepts multiple choices to select special situations in a person page, like: disabilities or chronic disease. Django rest framework requires a list and gives this error when I send other type like string.

  "special_situation":["Expected a list of items but got type \"str\"."]
  

  However when I check the options of the endpoint I don't get an indication of that requirement:

  HTTP 200 OK
  Allow: GET, POST, HEAD, OPTIONS
  Content-Type: application/json
  Vary: Accept
  
  {
      "name": "Special Situation List",
      "description": "API endpoint that allows special situations to be viewed or edited.",
      "renders": [
          "application/json",
          "text/html"
      ],
      "parses": [
          "application/json",
          "application/x-www-form-urlencoded",
          "multipart/form-data"
      ],
      "actions": {
          "POST": {
              "url": {
                  "type": "field",
                  "required": false,
                  "read_only": true,
                  "label": "Url"
              },
              "name": {
                  "type": "string",
                  "required": true,
                  "read_only": false,
                  "label": "Name",
                  "max_length": 50
              }
          }
      }
  }
  
  

  I'm using HyperlinkedModelSerializer and endpoint is called at:

  http://127.0.0.1:8000/myapi/person/
  

  and

  http://127.0.0.1:8000/myapi/special_situation/
  

  The end point is linked from person endpoint where I'm sending values based on the options of special_situation, the options for person end point also doesn't show the list requirement:

              "special_situation": {
                  "type": "field",
                  "required": false,
                  "read_only": false,
                  "label": "Special situation"
              }
  

  In the person module I've:

  special_situation = ParentalManyToManyField('needy.SpecialSituation', blank=True, verbose_name='special situation')
  

  And for SpecialSituation:

  @register_snippet
  class SpecialSituation(models.Model):
      id = models.AutoField(primary_key=True)
      name = models.CharField(max_length=50)
  
      panels = [
          FieldPanel('name'),
      ]
  
      def __str__(self):
          return self.name
  
      class Meta:
          verbose_name_plural = 'special situations'
  

  I thought the "type": "field" indicates a list it self but it's not acceptable in other endpoints without multiple choices. like in the charity end point.

  "charity":["Incorrect type. Expected URL string, received list."]
  

  full source code is availbe at: https://gitlab.com/uak/needy/-/tree/api_development

  so the issue is that there is no indication that this end point requires a list except in the error message. I would like to be able to detect accepted type before I submit data to be able to dynamically construct a form in my GUI app.

  I know I can manually detect the field name and create a list but would like a dynamic/automated without hard coding fields with different requirements.
• Add a custom link/model to wagtail's admin sub-menu

  Wagtail documentation explains how to:

  • Add an item to the admin menu
  • Add a group/submenu to the admin menu

  Let our model be CustomManager and its admin url be /admin/custom_manager/.

  Using a hook, we can add a link to our page on to the first level of the admin menu:

  @hooks.register('register_admin_menu_item')
  def register_edit_menu_item():
    return MenuItem( 'Custom Manager', '/admin/custom_manager/', classnames='icon icon-folder-inverse', order=1000)
  

  But how can we add this link to a sub-menu/group, when our model is not a wagtail model?
