9 – Get the paragraph fields of a content type in a loop in another page

I have added a paragraph in content type News.
I want the fields on this paragraph in my custom home page in a loop.
As The News Contents would be shown in a carousel in home page.
I am new to drupal. Can anyone help me?
I have tried using views. the content is rendered. but as the view has extra divs, the design breaks.
Drupal 9 using twig.

Using semantics view, i can modify or add classes to the div. but i needed to get rid of the outer two divs i.e. from container and views-view.html.twig. As the carousel is out of the view. and the view is acting like a single carousel entity.

Haskell: Implementing the data type LExpR as an instance of show

I am trying to implement the data type LExpr as an instance of show.

data LExpr = Var String        
                | App LExpr LExpr   
                | Lam String LExpr 

This is my code:

 instance Show LExpr where
      showsPrec d (Var str)   = showString' str
      showsPrec d (App e1 e2) = showParen (d>=6) $ showsPrec 6 e1  . showString " " . showsPrec 5  e2
      showsPrec d (Lam str e) = showParen (d>=5) $ showString ("\"++str++" -> ") . showsPrec 5 e

I am looking for some advice on how to further improve my code.

How to fix the taxonomy and custom post type slug/url

I have a custom taxonomy and post type.

When I click on a taxonomy item the slug changes to:


And that page is using taxonomy-developments.php

But when I click on an item there which is a custom post type item, the url changes to:


This uses single-property.php

I would have though the url should be:


Because I want to show the property belonging to that development and thus have the url indicate that.

The post type:

register_post_type('property', array(
    'supports'      => array('title', 'editor', 'thumbnail', 'page-attributes'),
    'rewrite'       => array('slug' => 'our-properties'),
    'has_archive'   => true,
    'public'        => true,
    'show_in_rest'  => true,
    'hierarchical'  => true,
    'labels'        => array(
            'name'         => 'Property',
            'add_new_item' => 'Add New Property',
            'edit_item'    => 'Edit Property', 
            'all_items'    => 'All Properties',


register_taxonomy('developments',array('property'), array(
    'hierarchical' => true,
    'labels' => $labels,
    'show_ui' => true,
    'show_admin_column' => true,
    'query_var' => true,
    'show_in_rest' => true,
    'rewrite' => array( 'slug' => 'developments' ),

8 – Cannot upload file of type image

I am experiencing a really strange behavior I have never seen before with Drupal. I am able to upload files of every type but not images. The files system is public. The problem appears on the local test server and on the live server.

Error message:
The image upload widget shows the standard error box logging:
**The file xyz.jpg could not be uploaded.

  • This value should not be null**

This issue appears on the whole site on every image of the file field widget within the backend.
Even the file upload for Drupal’s “File Archive” does just work with every other file type than ‘jpg’, ‘jpeg’, ‘gif’, ‘png’ file types.

The issue appeared after updating to the “web/” file structure while also updating the core to 8.8. I tried to update to 8.9.12 including every module installed but the error when trying to upload a file stays.

I rechecked all the settings regarding “tmp folder” and also tested the folder access rights (chown, chmod). It is set to 777.

I updated the database (drush updb) and also rebuild the cache (drush cr).

No PHP error log is created (not in Drupals Watchdog or the apache log).

I am sure that it is not a configuration issue as I am able to upload files that are not image files without problems. Another interesting bit is that when uploading a file it is actually created in the final sites/default/files location. The file also has the correct owner and access rights.

I could not find a related issue when researching nor I am able to come up with another idea. I even tried to change the file system to private, created new entities with image or file fields and tried different image upload widgets – nothing seems to work.

database – What type of data-base is good for storing records where each record potentially has hundreds of fields, and the fields are usually `null` values?

When I was in college, the only type of database we studied were relational databases using SQL.

However, I now have an application, where if you tried to use a relational-database, more than 90% of the cell-values would be null and tables would have thousands of columns.

Clearly, a relational database is the wrong choice.

My question is, what type of database is better suited to my application?

If you know what SQL is, then go to the next header/section-break.

In a relational database, everything is stored in spreadsheet-like tables.

Feel free to skip reading this section.

In an example of a relational database, a table recording data for apartment rentals might have the following columns:

  • Floor Area Lower Bound (e.g. 450 square feet)
  • Floor Area Upper Bound (e.g. 850 square feet)
  • Monthly Rent (e.g. $750.00)
  • Is Electric Bill is Paid by Landlord? (Boolean)
  • Is the water bill paid by the landlord
  • Street Address of the apartment (e.g. 123 somewhere lane)
  • etc…

I was thinking about creating a database for a job-applicants and job-classifieds.

Traditionally, job classifieds are stored as Unicode strings.
Computers have difficulty parsing and interpreting English.
Humans end up reading the job classifieds, and sorting the job classifieds “by hand.”

Suppose that a prospective job-applicant as no security clearance.
It would be nice if the computer would delete could all rows of the search results containing jobs for which a security clearance is required. This would save people time reading classifieds for jobs they are not qualified for.

The question is whether job J has at least one job mandatory/minimum qualification Q such that a human-being ,Sarah, does not have job-qualification Q

We are often working with 3-valued logic. In a generalized of the mathematical “law of the excluded middle“, One of the following 3 is always the case:

  • Jane has a commercial driver’s license.
  • Jane does NOT have a commercial driver’s license.
  • It is unknown whether Jane has a commercial driver’s license or not.

We want a database where:

  • Roles/Positions have qualifications.
  • Actors/Job-applicants have qualifications.

If a job requires at least 2 years of Java-programming, and Ian has 8 years of java programming, then we choose NOT to delete that job from the search results we show to Ian

I would prefer that bots filter and prune the search-space as much as possible.

A bot could run a search query, such as “furniture mover” using an traditional nothing-fancy search engine. After that, a bot could identify which job-qualification would split the search results most nearly in half. A 40%-60% split is better than 1% to 99%.

Maybe a commercial driver's license is a suitable job-qualification. After identifying an attribute to prune-on, the computer can ask the human something like, “do you have a commercial driver’s license?” The answer might cut the search space in half.

Every time the end user is asked a question about their qualifications, the computer stores the answer in a data-base.

A SQL table for job-applicants would have more than 2,000 columns (i.e. job qualifications). Examples of column headers are shown below:

  • Number of years of Network domain experience (float)
  • Number of years of experience operating fork-lifts (float)
  • Are you a licensed plumber (Boolean)
  • Do you have a Ph.D in psychology? (Boolean)
  • Are you a licensed in the United States to be a professional counselor (LPC)?
  • Number of years of experience writing computer code for front ends (float)
  • Do you have a CDL (commercial driver’s license)?

I am not willing to record, for every human being under the sun, whether that person has experience using a fork-lift or not, cooking Chinese food, or writing computer programs in java-script.

Perhaps we can “tag” each job-applicant.

  • Some users are “tagged commercial driver's license = yes
  • Some users are “tagged commercial driver's license = no
  • Some users do not have a tag for commercial driver's license at all.

What kind of data-base best supports what I am trying to do?

The website we are currently using,, has a maximum of something like 8 tags per question.

I would like to be able to support at least a dozen, if not a couple hundred, tags for each stage-role (job) or single stage-actor (job-applicant)
