I'm new in coding field. I decided to start a project with Django & Python, but I got stuck due to some errors. For the past 3 weeks, I tried to figure out what was the issue but couldn't find it. I will appreciate it if anyone help.
when I run my code, I get as an error, "TemplateDoesNotExist at /welcome_page/"
Everything as been specified but I'm still getting the same error
Here is the error page:
TemplateDoesNotExist at /welcome_page/
content of the welcome page:
Content of my the welcome page
my URLs :
URLS where I defined welcome page
My base content:
My base content
the place where the welcome page is calling from:
The place where the welcome page is calling from
My root to the welcome page from my C: drive:
My root to the welcome page from my C: drive
In your logout_request() view the last line is this:
return redirect("templates/welcomepage.html")
That's trying to redirect the user to a template. It should be redirecting to a URL.
In your urls.py the Welcome Page view has name="welcomepage" - this is what you use to refer to that URL. So change that line in your view to:
return redirect("welcomepage")
That will return the user to the "welcomepage" URL, which uses the views.welcome_page view, and the templates/welcome_page.html template.
By the way, if your welcome_page view is a class, as opposed to a function (I can't see it in your screenshot, so can't tell) then it's more normal in python to capitalise it: WelcomePage. Or WelcomePageView. Functions are lowercase (welcome_page).
If I see it right, you redirect to /templates/xxx.html but that path is not defined in your paths. The templates directory is the internal location, but the user can only see what is defined in the paths.
You should also better redirect ti the name of the page defined in the paths. Please post your settings.py maybe there is also a problem with the search path for templates.
I am creating a simple eBay like e-commerce website to get introduced with django. For removing an item from the watchlist, I placed two same links in two different HTML files, that is, I can either remove the item from the watchlist.html page or either from the item's page which was saved as listing.html. The url for both the pages look like this:
Remove from watchlist
Now, in my views.py, I want to render different pages on the basis of the request. For example, if someone clicked Remove from watchlist from listing.html then the link should redirect again to listing.html and same goes for the watchlist.html.
I tried using request.resolver_match.view_name but this gave me 'removeFromWatchlist' as the url namespace for both of these request is same.
Is there any way I can render two different HTML pages based on the origin of the url request?
Also, this is my second question here so apologies for incorrect or bad formatting.
You could check the HTTP_REFERER in the request.META attribute of the view to get the url that referred the request as so:
from django.shortcuts import redirect
def myview(request):
...
return redirect(request.META.get("HTTP_REFERER"))#Or however you prefer redirecting
https://docs.djangoproject.com/en/3.1/ref/request-response/#django.http.HttpRequest.META
I am trying to build a universal header file that I can include in each .html file on my site. My header contains several dropdown tabs, and one of the tabs is always highlighted (depending on which page the user is on). So I want to do something like a server side include for the header, but I also want to give it a variable so that it knows which tab to highlight, something like this:
<div class="topmenu">
<ul>
<someScript>
if (variable=="home") {
print "<li class='current'>";
} else {
print "<li>";
}
</someScript>

My server is IIS 7 and doesn't support PHP, and I don't want to rename all my files to *.asp so that I can use ASP. How could I go about this?
By the extension I guess you would use Classic ASP. Then something like this should work:
<!--#include file="header.asp"-->
You can put this in each file you want to have a header.
Of couse, you should create that "header.asp" page first ;)
For highligthing the tab of the page you're in, there're several methods.
IMHO, I suggest a clientside script to do that. JS or jQuery of course.
You could check the file name of the URL you are in and give the proper class to the tab so it will be highligthed.
Example ( jQuery needed ):
var currentPage = window.location.pathname.substring(url.lastIndexOf('/')+1);
if(currentPage == 'default.asp') $('li.homepage a').addClass('current');
This simple code retrives the file name and, by it, add a class to the corresponding element in your navigation.
Of course this is a conceptual script, you'd better adapt it to your page.
My Yii application has a particular section called 'Edit Profile' . It's a pretty data heavy section in the way a lot of data is pulled from db for this one .
However the problem is that I have tab pagination in this section . Because only this section uses tabs on the website I did not include the related CSS/Javascript files in the main layout header .These have been referenced in the view file itself . Because of this the tabs takes time to show up and the tab titles appear as a list first (for a second or two) and then get distributed into tabs with the correct UI . This is of course unacceptable behaviour . Is there any way to selectively include related js/css files into the header tag for this particular view or should I include it in main layhout file even though it won't be used in a lot of other places on the website thus possibly slowing down other pages .
Just specify the position for the file.
In your view where you are including the js or css :
// for js
Yii::app()->clientScript->registerScriptFile('url_of_file',CClientScript::POS_HEAD);
// for css
Yii::app()->clientScript->registerCssFile('url_of_file');
Recommended documentation: registerScriptFile() , and registerCssFile()
You can create your own layout in the layouts folder , where u can include all the required jquery scripts and css. U can then call your layout in the controller.
public function actionDoSomething(){
$this->layout = 'mylayout';
$this->render('myview');
}
I'm sure this topic comes up all the time,
But I can't seem to fine a concise answer.
I've got a vertical menu bar that I want to reuse in webpages (>20).
The Menu Bar is coded in HTML and uses uses: UL, LI, A, <Div> tags, and CSS. We need this:
Reusable
Maintainable
Scalable
So we don't have to modify all pages every time we add a page.
We'd rather avoid a coding approach if possible. We could live with just one master file that we edit as needed. Since we're using CSS and <div>s, I don't think frames scale for us. What can we do?
Server side includes are the way to go if you don't want to use a programming language.
They take this form:
<!--#include virtual="menu.html" -->
and will be inserted in the page wherever you put that tag in your HTML. It requires server side parsing, so your web server must have server side includes enabled. You can try it out, and if it doesn't work, contact your server host to see if you can get them enabled. If it's Apache, there's a method of enabling them via .htaccess files as well.
In order to do this, you'll have to use some server side technology. For instance you could...
include them in php
put them in the master page in .net
put this in a partial or a layout page in rails

Another solution would be to create all this using Javascript, but please don't do it like that :)
html:
<script type="text/javascript" src="hack.js"></script>
<div id="mymenu">
</div>
hack.js:
function createMenu(){
$("#mymenu").html("all the html of your menu");
}
Without any server side script or Javascript you can use object or iframe tags.

The only thing to care is to indicate target="parent" in links.
Hope it helps
Using a w3 script..
index.html
<!DOCTYPE html>
<html>
<script src="http://www.w3schools.com/lib/w3data.js"></script>
<body>
<div w3-include-html="header.html"></div>
<div w3-include-html="nav.html"></div>
<script>
w3IncludeHTML();
</script>
</body>
</html>
header.html
<h1>Title</h1>
nav.html
<h2>Your nav</h2>

And don't forget to test this code on your localhost.
I've done this two separate ways - one using server side (PHP) and one using Javascript includes (for demos that need to be able to run without any internet connection or server capabilities).
For PHP includes your pages will have to end with .php rather than .htm or .html, and these are very ideal to replace your header, footer, navigation, etc. Anything that is repeated on multiple pages.
Basically you would create your normal code then copy and paste the code you want to break out - in this example, your navigation - and save it in another file called (for example) inc_navigation.htm (this page can be called .htm).
Then in your actual pages you'd use the following code:
<?php include('inc_navigation.htm') ?>
That would insert your navigation at that point, if you had a change to make you'd make it to the .htm file and it would propagate to any page with that included.
For javascript includes you will have to include the following line at the top of every document where you want to include your navigation:
<script type="text/javascript" src="includes.js"></script>
Then you'll create a document called includes.js.
At the top of this document you'll declare your navigation variable:
var navigation = new Array(); // This is for the navigation.
Then a little ways down in that same document you need to actually outline your navigation code (the line numbers in the square brackets are crucial - keep them in order and start with 0 - you cannot have line breaks in this code so every line of code has to be a new line):
// ==================== Navigation ==================== //
navigation[0] = '<div id="tab_navigation">';
navigation[1] = '<ul id="dropline">';
navigation[2] = '<li><b>Home</b></li>';
navigation[3] = '<li><b>About Us</b></li>';
navigation[4] = '</ul>';
navigation[5] = '</div><!-- Close TAB NAVIGATION -->';
Then a little ways after that you'll actually insert the javascript that will put that code into your page (it doesn't actually put it there but rather makes it accessible in the page without actually altering the code of the .htm page - so if you view source you'll see the reference to the code not the code itself).
function show(i)
{
for (x in i)
{
document.write(i[x]+'\n')
}
}
Finally - in your .htm document, say for your index.htm page, you'll replace your navigation code (that you put in the above block called navigation) with this:
<script type="text/javascript">show(navigation);</script>
Where that name after SHOW and in the parenthesis is the name of your variable (declared earlier).
I have sites showing both methods in use if you'd like to see them just send me a message.
I was facing the same thing. Then, I created a new file for storing the html of the navigation bar.
I created a file navbar.html which had all my navigation bar code.
Then, in your main html file where you want navigation bar, just include this file by using jquery.
$(document).ready(function() {
$('#navigation').load('navbar.html');
});
Then at the place where you want navigation bar, just add this line:
<div id="navigation"></div>
As a modern answer to a six year old question: Web Components are specifically reusable HTML components, and Polymer is possibly the most popular implementation of it at the moment. Currently virtually no browser has native support for Web Components, so at the very least a Javascript polyfill is required.
If you would use PHP, all you have to do is use the include command, no coding beyond this one command.
Also, check out server side includes
So far one of the best solutions I have found is to model the menus after the Son of Suckerfish XHTML/CSS solution that is pretty well documented on the internet now combined with some logic on the server to render the unordered list. By using unordered lists you have a couple different options on how to output the results, but as long as the menu has some basic hierarchy you can generate it. Then for the actual page all you need to do is include a reference to the menu generating function.
I was searching for a way to write a reusable navigation menu that toggled(show/hide) when clicking a button. I want to share a solution that worked for me in case anyone else is looking to do the same. This solution uses jQuery, html, and css.
Add this line of code to your head tag in your main index.html file:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Add div for your nav in body tag:
<div id="mySidenav" class="sidenav"></div>
<script>
$(document).ready(function(){
$("button").click(function(){
$("#mySidenav").load("nav.html").toggle().width("400pt");
});
});
</script>
Create a html file that will be where your navigation menu resides. My file is called nav.html and inside the file the contents look like this:
have you found your one true musubi?`
item2
item3
