Everything went fine expect the weather icons in the forecast .Previosly the same icon was used for all changing weather but how can i write code so that different icons can be seen for varying climates Here is my Jquery code : $(document).ready(function () { var content = $('#patti').text(); var iconurl = 'http://l.yimg.com/a/i/us/we/52/' +content+ '.gif'; $('#wicon').attr('src', iconurl); $.each($('.icon1'), function( ) { var content2 = $(this).text(); //console.log("content=",content2); var iconurl2 = 'http://l.yimg.com/a/i/us/we/52/' +content2+ '.gif'; console.log(iconurl2); var final = $('.wicon2').attr('src', iconurl2); console.log(final) }); }); My index.html file for the forecast of 7 days : <div id="container-fluid"> <div class="row"> {% if form.is_valid %} <div class="col-sm-3"> <div class="container text-center hi" style="background: whitesmoke"><br> <iframe class="clock" src="http://free.timeanddate.com/clock/i66pyson/n1906/fn4/tct/pct/ftb/ta1" frameborder="0" width="101" height="18" allowTransparency="true"></iframe> <h4 style="color: whitesmoke">{{text}}</h4> <br> <div id="icon"><img id="wicon" src="" alt="Weather icon"></div><h2 id="thendi" style="color: whitesmoke"><strong>{{temp}} °C</strong></h2> <br> <!--<p style="color: whitesmoke">{{date|slice:':3'}}</p>--> <p id="patti" style="visibility: hidden">{{code}}</p> </div> </div> {% endif %} <br> <br> <!--forecast--> <div class="col-md-offset-9"> <div class="row"> {% for obj in forecast|slice:":7" %} <div class="col-sm-offset-5 text-center" style="color: #7a43b6"> <div class="card"> <p style="color: whitesmoke"> {{obj.date}}</p> <p style="color: whitesmoke">{{obj.text}}</p> <div class="card-content"> <p class='icon1' style="visibility: hidden"> <div id="icon2"><img class="wicon2" src="" alt="Weather icon"></div> <p style="color: ... -

How to create a website that automatically updates itself daily by scraping data (Python, Django, Webscraping)?
My goal is to build a website that shows price charts for products on Amazon. The data should be represented visually with a price chart (time-series data), so that users can see how prices have changed over time. The price has to be updated daily for every product page. I plan to scrape price data with my python script in the backend - the script should be executed by a cronjob. The main functions of the script will be to scrape pricing data (with beautifulsoup) for every product page and to append that data to the database. I am really new to python web applications. What would be the best way to achieve my objective? Django? Or are there any frameworks that are better for my use-case ? PS: I dont't want to use Amazon's API. -

Django - Returning new form output in new line without overwriting previous output
I have been developing a bot using python and nltk and it works on the command line. Now I want to capture input using a web page, and I am transferring the logic to Django. I will use a simpler example to demonstrate the problem I have. In my index.html, I have a user entering a question into a single input box and upon clicking send, the view simply returns what they entered: their 'question' and 'answer' below the input box. The problem is when they enter a new question it overwrites the previous one, but I would want the new question and answer to appear below the previous one as in a chat thread. If maybe you do not get what I mean, I'll use images. This happens: when the user enters first chat message. Then when the user enters second chat message. What I want is this: to have both of them as a thread and not two overwriting one I have just started using Django with this project and while with the cmd I could just use while True: I am a bit stumped on how to do it using the views and templates in Django. Here's ... -
PythonAnywhere 'function' object has no attribute 'get_extra_actions' Django Rest
I've made a basic application with the Django framework and PythonAnywhere is not liking my code for some reason. When I ran the autoconfiguration for manual setup, I got an error that Django rest framework was required and the setup exited prematurely. The error was: ModuleNotFoundError: No module named 'rest_framework' I got into the venv and finished setup, though there were a few issues here and there. I manually installed djangorestframework from Github so that anything would show up, but I am still getting an unknown error that I have traced back to the routers.py file. The content of the error can be found on: nebrethar.pythonanywhere.com A sample of my routers.py file is as follows: def get_routes(self, viewset): known_actions = list(flatten([route.mapping.values() for route in self.routes if isinstance(route, Route)])) extra_actions = *****viewset.get_extra_actions()***** not_allowed = [ action.__name__ for action in extra_actions if action.__name__ in known_actions ] I have starred out the section that causes the error. Most of the fixes I've run into have been installing packages but I've been stumped. -

Django-Viewflow, customize archive view
I am trying to customize the default /workflow/archive/ view from Viewflow. (as in http://demo.viewflow.io/workflow/archive/) I need to remove some of the columns and add some additional ones specific to my task. I can't seem to find an easy way. I have been digging and have found that I can try to override the class viewflow.frontend.views.AllArchiveListView and adding the mapping url('^test/', AllArchiveListView.as_view()) but I get no data when doing that (seems like the flow_classes internal parameter is empty when it gets called like that) I have also tried to create the viewflow/site_archive.html template but seems overkill. Any ideas that may point me in the right direction would be highly appreciated! -

Django issues passing variable from view to template javascript
Description: I have an view that is called every second to display temperature data to temperature.html from the backend of my project. In order for it to fulfill its purpose it needs an variable which will be passed through render to the template, where i want it to be used as an Javascript variable in order to update the canvas-gauge that I am using within the template to display temperature data. Problem: My view is being called through the console at the correct interval, so that is not the issue. However, what is not happening is the variable is not being passed through to the template at all. I have tried to have the template display the variable to see if the variable is at least being sent to the template. Answer: It is not reaching the template at all, variable outputs "undefined". I have passed forms in this manner through my other views in the same way I am attempting to pass this variable, and it works correctly. I do not understand where I am mistaken with my template/view. I have researched for at least 6 hours in attempt to find the solution and clearly I have not found ... -
