I have a simple "hello world" VueJS app I'm trying to get working:
<!doctype html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="https://unpkg.com/vue"></script>
</head>
<body>
<div id="app">
Message: {{ message }}
</div>
<script>
var vm = new Vue({
el: "#app",
data: {
message: "Hello, world"
}
});
</script>
</body>
</html>
When I load this file in the browser, off my local disk (ie: file:///home/user/vue-project/index.html), it loads and "Hello, world" is displayed.
However, if I try to take the same file and serve it through the python flask development server, or through gunicorn, {{message}} renders blank.
Does anyone know what might be causing that to happen?
flask renders its variables with jinja2 which uses {{ variable }} as its parsing delimiter
render("mytemplate.html",message="Hello") would replace all {{ message }} blocks with "Hello" before any javascript is handled ... since you dont define message it is simply an empty string... you will need to configure vue to use alternative delimiters (I use [[ message ]])
<!doctype html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="https://unpkg.com/vue"></script>
</head>
<body>
<div id="app">
Message: [[ message ]]
</div>
<script>
var vm = new Vue({
el: "#app",
delimiters : ['[[', ']]'],
data: {
message: "Hello, world"
}
});
</script>
</body>
</html>

I am trying to display my html files using python alone. Such as I would python code.py and I would be able to access my html at localhost:8080
html files are static files that access each other. For example, index.html directs to contact.html and all of them access css folder.
How do I open my html files so it displays it on the webpage?
below is what I have so far.
html_file = []
with open("index.html", "r") as f:
for line in f.readlines():
html_file.append(line)
Is there way to do python code.py and when I access localhost:8000 that would show me the code? and I can access each page.
here is an example html file.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>title</title>
<link rel="stylesheet" href="./css/style.css">
</head>
<body>
<header>
<img class="resize" src="./pictures/logo.png" alt="logo">
<nav>
<ul class="nav-links">
<li class="active">Home</li>
<li>Contact</li>
</ul>
<script src="https://code.jquery.com/jquery-3.5.0.js"></script>
<script type="text/javascript">
$(document).on('click', 'ul li', function(){
$(this).addClass('active').siblings().removeClass('active')
})
</script>
</nav>
</header>
</body>
</html>
There's way to do so using the python web frameworks like Flask or Django. In a typical flask scenario your code would look like this:-
1) Install flask:-
pip install flask
2) Write your code.py like this:-
from flask import Flask, url_for
from flask import render_template
app = Flask(__name__)
#app.route('/')
def index():
return render_template('hello.html')
3) Next create a templates folder inside which put your html file which I have named it to be hello.html
templates > hello.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>title</title>
<link rel="stylesheet" href="./css/style.css">
</head>
<body>
<header>
<img class="resize" src="./pictures/logo.png" alt="logo">
<nav>
<ul class="nav-links">
<li class="active">Home</li>
<li>Contact</li>
</ul>
<script src="https://code.jquery.com/jquery-3.5.0.js"></script>
<script type="text/javascript">
$(document).on('click', 'ul li', function(){
$(this).addClass('active').siblings().removeClass('active')
})
</script>
</nav>
</header>
</body>
</html>
4) Your directory structure would look like this:-
/code.py
/templates
/hello.html
5) Run python code.py and you can see your page on localhost:5000.
learning how to use angular and python on atom text editor
this is my angular code in index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body>
<div ng-app="myApp" ng-controller="customersCtrl">
{{myData}}
<!-- <ul>
<li ng-repeat="x in myData">
{{x.name}},{{x.age}}
</li>
</ul> -->
</div>
</body>
</html>
<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
$http.get('test.py').then(function(response) {
$scope.myData = response.data;
});
});
</script>
and the python code is as below in test.py:
import json
message = "Hello World"
#test = [{'name':'sample1','age':'24'},{'name':'sample2','age':'25'}]
print json.dumps(message)
the commented code is what i really want to do, but i am not able to get the simple code work either.
when i run the code on live server, this is the output i see on the page http://127.0.0.1:3000/index.html:
import json message = "Hello World" #test = [{'name':'sample1','age':'24'},{'name':'sample2','age':'25'}] print json.dumps(message)
i need get context in react using django
but i cant do it
this is my code
in my jsx
<h1>{{titulo}}</h1>
<h2>{{ejemplo}}</h2>
in my template:
{% load staticfiles %}
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
</head>
<body >
<div id="app"></div>
<script type="text/javascript" src="{% static 'bundle.js' %}"></script>
</body>
</html>
in my view py:
def registro (request,giro):
reg = 'Registro Normal'
if giro==1:
reg='Registro Especial'
context = {
'ejemplo':'tests',
'titulo':reg
}
return render(request,'home/registro.html',context)
but does not render and wild error appeared :(
Uncaught ReferenceError: titulo is not defined
The Django context is only when the template is rendered on the server. React uses Javascript which means it's rendered on the browser. If you want to use Django variables in your React app, you will need to set those variables in Javascript (making sure to do so before bundle.js is imported).
So your template might look something like this:
{% load staticfiles %}
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
</head>
<body >
<div id="app"></div>
<script type="text/javascript">
/* Put your context vars here. I recommend putting them under
a variable to avoid naming conflicts.
*/
var context = {
titulo: '{{titulo}}',
ejemplo: '{{ejemplo}}'
};
</script>
<script type="text/javascript" src="{% static 'bundle.js' %}"></script>
</body>
</html>
Then in React you can reference context.variable to get the value you need.
This is urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.login_page, name='login_page'),
]
my views.py like this
def login_page(request):
return render(request, 'mileage/login_page.html', {})
this is my html code
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, width=device-width" >
<meta charset="UTF-8">
<title>Test</title>
<link rel="stylesheet" href="{% static 'css/style.css' %}">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js">
</script>
</head>
<body bgcolor="#4599e8">
<div class="title"><span><h1>Test</h1></span></div>
<div class="home_password">
<div class="password"><input type="password" name="password" placeholder="Password"></div>
<div class="button"><button>OK</button></div>
</div>
</body>
</html>
And start server, but my localhost:8080/ shows only html text not page.
Using Chrome Developer Console, I checked element.
<html>
<head></head>
<body>
<pre style="word-wrap: break-word; white-space: pre-wrap;">
"
my html code here.
"
</pre>
</body>
</html>
I don't know how to solve it.
Who is inserting all your html code inside the pre tag is your browser because it probably receives a Content-type: text/plain header with the response and it thinks you want to see the html code instead of the rendered webpage.
Try making a test using:
render(request, 'mileage/login_page.html', {}, content_type='text/html')
If it works, set the DEFAULT_CONTENT_TYPE constant to 'text/html' in your settings.
DEFAULT_CONTENT_TYPE
Default: 'text/html'
Default content type to use for all HttpResponse objects, if a MIME
type isn’t manually specified. Used with DEFAULT_CHARSET to construct
the Content-Type header.
Probably an environment variable is messing you up with this, It's weird that it has a default 'text/plain' content type set.
This is my first crack at Angular. I'm posting JSON data to an html page using Angular.js. I know I'm missing something but can't seem to get it working. Below is the html. I have a python script posting to the same URL below.
<!doctype html>
<html lang="en" ng-app id="ng-app">
<head>
<title>File Analysis</title>
<script src="js/angular.js"></script>
<script>
var myApp = angular.module('fileAnalysis', []);
myapp.controller('PostsCtrlAjax', function($scope, $http)
{
$http({method: 'POST', url: 'http://test.com'}).success(function(data)
{$scope.posts = data;}) // response data
});
</script>
</head>
<body>
<h1>You should begin to see new files being analyzed!</h1>
<div id="ng-app" ng-app ng-controller="PostsCtrlAjax">
<div ng-repeat="post in posts" >
<h2>
<a href='{{post.url}}'>{{post.title}}</a>
</h2>
<td>
{{post.filename}}
</td>
</div>
</body>
</html>
