How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

Position Layout property in CSS

Hello, World! In this article, we will try to grasp the concepts of one of the trickiest and crucial topics in CSS.

Position layout property in CSS is solely used to place and position elements respectively in an HTML document. They assign respective positions to HTML elements so that the overall design of our page is maintained and managed well.

The widely used positions property in CSS are as follows:

1. Static position:

When an HTML element gets assigned with

staticposition, the various position properties likeleft,right,topandbottomdoesn’t work. Elements in an HTML document carry static position by default.

Let’s copy and paste the code below in an IDE to view what’s happening.

<!DOCTYPE html>
<html lang="en">
  <head>
    <style>
      #Section {
        height: 200vh;
        width: 800px;
        border: 5px solid blue;
        background-color: cyan;
        font-family: monospace;
        font-size: 2rem;
        text-align: center; 
      }

      #Div1, #Div2, #Div3 {
        border: 4px solid red;
        font-size: 1.5rem;
        width: 200px;
        height: 100px;
        text-align: center;
        display: inline-block;
      }

      #Div2 {
        position: static;
        left: 20px;
        top: 50px;
      }
    </style>
  </head>
  <body>
    <section id="Section">
      <p>This is Section</p>
      <div id="Div1">
        <p>This is Div 1</p>
      </div>
      <div id="Div2">
        <p>This is Div 2</p>
      </div>
      <div id="Div3">
        <p>This is Div 3</p>
      </div>
    <section>
  </body>
</html>

Upon adding position property

staticto the selector idDiv2, we saw that the position ofDiv2box didn’t change. Hence, we can conclude that elements with positionstaticdoesn’t get affected byleft, right,toporbottomproperties.

2. Relative position:

When an element gets assigned with position

relative, the position properties likeleft,right,top andbottomaffects the element’s position in the page relative to its normal position asstatic.

Let’s copy and paste the code below to

Div2selector to replace the previous position property.

#Div2 {
        position: relative;
        left: 20px;
        top: 50px;
      }

We can see that the

Div2box changed its position relative to its normal orstaticposition, i.e.20pxfrom theleftand50pxfrom thetop. Upon applyingrelativeposition property to an element, other contents in the same box won’t get affected and change positions

3. Fixed position:

This position property is used to freeze an element in a particular location of the page so that scrolling doesn’t affect the visibility or location of the element. When we apply

fixedvalue to a selector, it gets removed from the flow of the HTML document, i.e. the selector element gets uprooted from its actual position, becomes relative to the entire viewport, and doesn’t get scrolled.

Let’s copy and paste the code below to know the difference.

<!DOCTYPE html>
<html lang="en">
  <head>
    <style>
      #Section {
        height: 400vh;
        width: 800px;
        border: 5px solid blue;
        background-color: cyan;
        font-family: monospace;
        font-size: 2rem;
        text-align: center; 
      }
      #Div1, #Div2, #Div3 {
        border: 4px solid red;
        font-size: 1.5rem;
        width: 200px;
        height: 100px;
        text-align: center;
        display: inline-block;
      }
      #Div2 {
        position: fixed;
        left: 0;
        top: 0;
      }
    </style>
  </head>
  <body>
    <section id="Section">
      <p>This is Section</p>
      <div id="Div1">
        <p>This is Div 1</p>
      </div>
      <div id="Div2">
        <p>This is Div 2</p>
      </div>
      <div id="Div3">
        <p>This is Div 3</p>
      </div>
    <section>
  </body>
</html>

After scrolling, we can see that the id

Div2gets fixed in the topmost corner of the document.

4. Absolute position:

Just like

fixedposition, theabsoluteposition property removes selectors from the flow. As the element gets removed from its normal position, the parent element doesn’t regard it as its child anymore. The element becomes relative to the document.
