I am using django-easy_pdf to reder pdf for my reports and would like to know how to display a page footer.
In the django-easy_pdf's source code this piece of code is used to display the page number
<div id="footerContent">
{%block page_foot%}
<pdf:pagenumber />
{%endblock%}
</div>
What I would like to know is:
How to display the footer properly
Start with page number 1
As I have copied the code, it does not display as a footer and the page starts with 0
What am I missing?
UPDATE
I tried this code from here but I can't make it work, seems useful though
<html>
<head>
<style>
.footer { position: fixed; bottom: 0px; }
.pagenum:before { content: counter(page); }
</style>
</head>
<body>
<div class="footer">Page: <span class="pagenum"></span></div>
</body>
</html>
UPDATE 2
I now know what I did wrong, I was missing the #page css and that is why It's not working, I only have the #frame footer
The correct CSS:
#page {
size: {{ pagesize }};
margin: 1cm;
#frame footer {
-pdf-frame-content: footerContent;
bottom: 0cm;
margin-left: 18cm;
margin-right: 0cm;
height: 1cm;
}
}
Then just call it normally(the first snippet)
To display footer correctly make sure that in your template in css styles you have:
#frame footer {
-pdf-frame-content: footerContent;
}
-pdf-frame-content should be pointig to id of your footer container.
You can add the next code in your tempate:
{%block page_foot%}
<div style="display: block;margin: 0 auto;text-align: center;">
page: <pdf:pagenumber />
</div>
{%endblock%}

I'm trying to add a "loader" while my flask application runs a task.
Here is my HTML for for my button
{% extends "base.html" %}
{% block head %}
{# <link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='styles/leaf.css') }}"> #}
{% endblock %}
{% block content %}
<div id="loader"></div>
<div id="vo_budget_file_settings">
{# Upload Final CRO Budget File #}
<p>Please upload the final CRO budget File</p>
<form class="" action="/generatecleanbudgetfile" method=POST enctype=multipart/form-data>
<input type="file" name="data_file" accept=".xls, .xlsx, .xlsm"/>
<input type="submit" value="Begin Format" onclick="loading();"/>
</form>
</div>
<script type="text/javascript">
function loading(){
$("#loader").show();
}
</script>
{% endblock %}
Here is the CSS that I've added:
#loader {
border: 16px solid #f3f3f3; /* Light grey */
border-top: 16px solid #3498db; /* Blue */
border-radius: 50%;
width: 120px;
height: 120px;
animation: spin 2s linear infinite;
}
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
Any ideas on how to call this correctly?
Make it visible from the start, without ever showing it with javascript. Then hide it with js like so:
$(document).ready(() => {
$("#loader").hide();
})
EDIT: I now realize you said on button click in the title. I am assuming you want to hide the loading screen on button click? If not correct me in a comment. Otherwise, use this code:
$("#button").click(() => {
$("#loader").hide();
})
P.S.
Your script should be at the bottom of the body, and your CSS and JS (and my code) reference #loader, when the body has <div id="loading">
I have linked my css file in 'main/static/css/style.css' and my pages are in 'main/templates/main/pages.html'.
But the CSS is not working for some pages such as the h2 tag is not taking the style.
base.html
{% load static %} <link rel="stylesheet" href="{% static 'css/style.css' %}">
privacy.html
{% extends 'main/base.html' %}
{% block content %}
<div class="main">
<h1><b>Privacy</b></h1>
<div style="height:35px" aria-hidden="true"></div>
<div class="text_para">
<h2 class="h2_privacy">Mission</h2>
<p>paragraph<p>
.......
style.css
.main {
-ms-flex: 70%; /* IE10 */
flex: 70%;
background-color: white;
padding: 20px;
}
.text_para {
margin-right: 5%;
text-align: justify;
}
/*heading h2 for privacy page*/
.h2_privacy {
color: black;
font-family: 'Lucida Calligraphy', sans-serif;
}
First you need to make sure CSS is loading properly (e.g. check from network section of browser dev tool).
Second you need to make sure the element is in the page and has the correct class matching CSS file.
Check these two and update your question if you didn't find the problem.
Sorry guys I was inactive and thank you.
And yes I have found the answer on stack overflow itself, actually I don't close my tabs so I think every time I refresh the page it does not refresh totally.
I just had to do ctrl + f5 to bypass the cache and the css would load with the updates.
I am using Flask and therefore Jinja2 to dynamically create a web page.
When I use the render_template function the resulting web pages pick up my css styles normally and do as I expect with some strange exceptions.
For example, the following css and html code is working 100% as intended:
CSS:
.intro {
font-family: monospace;
font-size: 24px;
color: #455934;
padding-top: 30px;
padding-right: 50px;
padding-bottom: 5px;
padding-left: 50px;
}
HTML:
<p class ='intro'>
Hello
</p>
However when using a ``Jinja2``` template:
<p class ='intro'>
{{title}}
</p>
The css style for this class is ignored.
This is not true for any other styles in the same css file and template, for reference the whole template looks like this and the styles for div containers, background, etc. work as intended:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<link rel= "stylesheet" type= "text/css" href= "{{ url_for('static',filename='gemuese_style.css') }}">
<title>{{title}}</title>
</head>
<body>
<div class="outer">
<div class="middle">
<div class="inner">
<p class ='intro'>
{{title}}
</p>
<ul>
<li>{{result}}</a></li>
</ul>
</div>
</div>
</div>
</body>
</html>
Edit:
Some testing has shown me that the style seems to work depending on the variable jinja renders. The template is rendered based on the output of different functions who generally return a list of a string and another list. The string is then used to fill in the {{title}} part where the css is failing.
For some functions it does work but I am not sure why because there is no difference in the return format.
Edit2:
Look at the difference between This rendered template and this one.
I want to create multipleselecetfild that each selection referin to each choice appears below the image.
I used the django MultiSelectField to create a form to have multiple select options.
These are my files:
models.py
class Profile(models.Model):
cat_choices = (
('Internships', 'Internships'),
('Scholarships', 'Scholarships'),
('EntranceExams', 'EntranceExams'),
)
category=MultiSelectField(choices=cat_choices,default='none')
profile.html
<!DOCTYPE html>
<html>
<body>
<style>
div.item {
vertical-align: top;
display: inline-block;
margin-right: 50px;
text-align: center;
width: 120px;
}
img {
background-color: grey;
}
.caption {
display: block;
}
</style>
<div class="item">
<img src="internship.png">
<span class="caption"><input type="checkbox" name="Internship" value="Internship"></span>
</div>
<div class="item">
<img src="jobs.png">
<span class="caption"><input type="checkbox" name="Jobs" value="Jobs"></span>
</div>
<div class="item">
<img src="scholarship.png">
<span class="caption"><input type="checkbox" name="Scholarship" value="Scholarship"></span>
</body>
</html>
I created a form called profile_form with the category field.
In html, I wanted my form to appear with an image on the top and just a check button below the image, with the check button refering to each cat_choices in the category. Something like this
!In the image I used html to display it.
How do I write this html page in django such that each check button refering to each choice appears below the image?
I can't locate this element.. I'm trying to un-check the history box and dl box (they're checked by default)
from selenium import webdriver
import time
chrome_path = r"C:\Users\Skid\Desktop\chromedriver.exe"
driver = webdriver.Chrome(chrome_path)
driver.get("chrome://settings/clearBrowserData")
driver.find_element_by_xpath("""//*[#id=delete-browsing-history-checkbox"]""") #unchecks history
driver.find_element_by_xpath("""//*[#id="delete-download-history-checkbox"]""") #unchecks dl history
This is the page source that someone wanted me to update.

driver.find_element_by_xpath is just looking for the checkbox and returning it as WebElement. You want to click on it to unchecked it
driver.find_element_by_xpath("""//*[#id="delete-browsing-history-checkbox"]""").click()
Also, you forgot apostrophes in the first xpath after #id=. It should be like in the example above.
Edit
You can try locating the checkbox by id
driver.find_element_by_id("delete-browsing-history-checkbox").click()
Edit 2
The checkbox are inside iframe. You need to switch to it first
driver.switch_to.frame("settings") # switch to the iframe by name attribute
# driver.switch_to.frame(driver.find_element_by_name("settings")) # should also work
driver.find_element_by_id("delete-browsing-history-checkbox").click()
driver.switch_to.default_content() # switch back to main window
Can you add to your question what you get as body from selenium?
driver.get("chrome://settings/clearBrowserData")
driver.page_source
If I check the source code in Google Chrome of this page I get:
view-source:chrome://chrome/settings/clearBrowserData
<body>
<div id="navigation"><iframe src="chrome://uber-frame/" name="chrome" role="presentation"></iframe></div>
<div class="iframe-container"
i18n-values="id:historyHost; data-url:historyFrameURL;"
data-favicon="IDR_HISTORY_FAVICON"></div>
<div class="iframe-container"
i18n-values="id:extensionsHost; data-url:extensionsFrameURL;"
data-favicon="IDR_EXTENSIONS_FAVICON"></div>
<div class="iframe-container"
i18n-values="id:settingsHost; data-url:settingsFrameURL;"
data-favicon="IDR_SETTINGS_FAVICON"></div>
<div class="iframe-container"
i18n-values="id:helpHost; data-url:helpFrameURL;"
data-favicon="IDR_PRODUCT_LOGO_16"></div>
<script src="chrome://chrome/strings.js"></script>
<script src="chrome://resources/js/i18n_template.js"></script>
</body>
It might be necessary to find another way to do it, if your driver cannot see this node.
Edit
In the source code you posted as page_source returned from selenium, there isn't the node you are trying to find.
After doing a find_element_by... all you get is the element. You also need to have a .click() on that element.
Either:
elem = driver.find_element_by_xpath("""//*[#id=delete-browsing-history-checkbox"]""")
elem.click()
or:
driver.find_element_by_xpath("""//*[#id=delete-browsing-history-checkbox"]""").click()
Btw, you could just use find_element_by_id("delete-browsing-history-checkbox") in your case.
Also, I don't think selenium works on non-web pages. So chrome settings and Firefox's about:config pages (for example) don't work with selenium.
