Anchor tags not working in DJANGO project do to Javascript file
I have a project with many anchor tags and urls that connect many apps and pages. I also have a javascript file with some functions and DOM events to make somethings in my project. If I add a the script element to my project base.html (thats extended to all my html files) at the head of my base document like this it doesnt load the javascript file and it lets me use the anchor tags normal. But if I add <script **defer ** src="{% static '/js/script.js' %}"> to the element it loads the javascript file but it doesnt let me use the anchor elements. I have tried adding the javascript tag at the end of the base.html before the and it loads the javascript file but it doenst -
How to create popover survey like Hotjar using javascript on client website?
I have been using Django to create post purchase form, much like Google Form, using iframe to embed the form to the clients website. But then I saw Hotjar and how they implement their form as a popover survey. In Hotjar, after the form is created, Hotjar gives a javascript trigger that can be pasted into the clients website. I can create those stuff on my own website, but I am a bit lost on how those can be implemented on another website using javascript trigger. Does anyone have any tips on how to go on about implementing it myself? P.S. I am not interested in tracking features of Hotjar, just survey. So far I thought of creating Django templates and views to create questions and answers, and based on the inputs, then convert it into javascript and save it to Google Cloud Storage. I thought maybe I can load it on clients website using Javascript. But not sure how or whether it is even a good idea. Basically, I just want the client to paste some javascript code. And in doing so the forms (Questions, answers, and buttons) I created would appear at the bottom right corner of their … -
django.http.request.RawPostDataException on file upload
When I try to upload a file to my Django application and try to get the body of the request, I get this error. File "/docs/geon/tenv/lib/python3.10/site-packages/django/http/request.py", line 330, in body raise RawPostDataException("You cannot access body after reading from request's data stream") django.http.request.RawPostDataException: You cannot access body after reading from request's data stream Then I tried using the debugger to inspect the middleware by creating a simple middleware that does nothing and adding it to the topmost place in the list of middleware, then adding a breakpoint just after entering the process_request function. Then I inspected the 'body' attribute of the request and it is RawPostDataException("You cannot access body after reading from request's data stream") Apparently, something is modifying the request before it gets to middleware at all, and if the body is empty, it should be an empty string and not raise an error. I don't know which stack before middleware to look. I have restframework installed in app if it means something -

Doctor Appointment Booking Using Django Forms
I am new to Django. I was trying to built a basic Dentist website which can be used by Patients for booking appointment, as a practice project. The problem I am facing is that I am unable to show available time slots dynamically, to prevent duplicate bookings. The time slot field comes up blank. I tried building logic in the constructor of the Django form itself, so that only available time slots are shown when a user selects a date. The Django form is: `from django import forms from django.forms.widgets import DateInput from .models import Appointment class DatePickerInput(DateInput): def __init__(self, *args, **kwargs): attrs = kwargs.get('attrs', {}) attrs.update({'data-provide': 'datepicker','data-date-start-date': '0d'}) kwargs['attrs'] = attrs super().__init__(*args, **kwargs) class AppointmentForm(forms.Form): first_name = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'class': 'form-control ', 'placeholder': 'First Name'})) last_name = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'class': 'form-control ', 'placeholder': 'Last Name'})) age = forms.IntegerField(widget=forms.NumberInput(attrs={'class': 'form-control ', 'placeholder': 'Age'})) date = forms.DateField( widget=DatePickerInput( attrs={'class': 'form-control datepicker px-2', 'placeholder': 'Date of visit'} ) ) time_slot = forms.ChoiceField(choices=[('', 'Select Time Slot')] + [(option, option) for option in [ '09:00 AM', '10:00 AM', '11:00 AM', '12:00 PM', '02:00 PM', '03:00 PM', '04:00 PM', '05:00 PM', '06:00 PM', '07:00 PM', ]], widget=forms.Select(attrs={'class': 'form-control'})) contact_number = forms.CharField(max_length=15, widget=forms.TextInput(attrs={'class': 'form-control ', 'placeholder': 'Contact Number'})) … -
Bokeh YearsTicker and still month on the ticker sometimes
I am using Bokeh for some charts in a Django project. For instance: [![This one is fine, showing YYYY on the x axis.][1] However, when I restrict the period of time to display (thanks to a DateRangeSlider), years are then displayed as "1/YYYY" [![This one is bad][2]][2] Axis are defined as follows: plot.yaxis.formatter = NumeralTickFormatter(format="€0,0") plot.xaxis[0].formatter = DatetimeTickFormatter(years="%Y") plot.xaxis[0].ticker = YearsTicker() Has anyone a clue of how to always have tickers as YYYY?

Linking error for c++: multiple definition of static inline function [closed]
I have two files I am compiling together using CMake (smallest example that produce the error): main.cpp #include "lib.h" int main() { return -1; } test.cpp #include "lib.h" CMakeLists.txt cmake_minimum_required(VERSION 3.25) project(proj) set(CMAKE_CXX_STANDARD 20) add_executable(proj main.cpp test.cpp) Now through a couple of inclides the lib.h file includes a file where the problem occurs: problematic.h #ifndef problematic_H_ #define problematic_H_ namespace p{ struct s{ // some code static inline thread_local someReturnType problemFunction{}; // some code }} Here I get the error: "multiple definition of `TLS init function for ...problemFunction...". I get the error on my Windows computer where I am using Clion with g++ from MinGW with gcc 9.3. First of all when compiling on my Mac it works fine. Second with my understanding of static inline there should be a different identifier for the function *problemFunction * in each of the two compilation units (files), and thus no multiple definitions. Third, since the * problemFunction * is in the header only library I do not want to change anything in there, I believe the error is somehow in my build setup. Any help would be much appreciated. -

ttyname_r on the same file descriptor from the same terminal does not return the same stream/tty on linux
I have a cpp application (process A) that obtains the terminal associated with the fd of stdin. int ttyName = ttyname_r(fileno(stdin),..........). When I run this process A directly, fileno(stdin) is 0 and ttyname_r on this returns 0 with the buffer set to 'dev/pts/0'. From the same terminal I have two different processes - process B and C spawning process A. I do not have control on what goes in B and C. Process B is launched by a bash script and I believe is a node.js process. Process C is a cpp application that spawns A by fork() and execv(). From the same terminal, when I launch processes B and C (either in bg), the ttyname_r call made by the spawned process A is different between B and C. From B, the ttyname_r call doesn't succeed and returns 25 (ENOTTY). From C, ttyname succeeds but the buffer is set to 'dev/pts/4'. I would expect the tty/stream returned on the fd of stdin to be the same i.e dev/pts/0 when called by multiple processes but all launched from the same terminal. I am currently reading the env 'SSH_TTY' to get the tty associated with the terminal and that seems to be … -

C/C++: Why does an iostream allocate more memory at runtime than printf?
I noticed this today and thought it was interesting: I compiled a basic "hello world" first in C and then in C++ #include <stdio.h> int main() { printf("a\n"); return 0; } #include <iostream> int main() { std::cout << "a" << std::endl; return 0; } And ran both of them through valgrind. The C version (even when compiled with g++) showed 1,024 bytes allocated, while the C++ version showed 73,728 bytes allocated That seems like a pretty massive difference -- what exactly is going on there? And a second thought, why is even a full kilobyte needed to run the C version? Thanks anyone who can help me understand! Update: Thanks everyone for your responses! It looks like including <iostream> has a one-time initialization cost of a little over 72,000 bytes, and the cout itself only uses the same kilobyte as printf. Just for kicks, I wrote the following and tested it: #include <stdio.h> class minified_output_stream { void output(const char* text) { printf(text); } public: minified_output_stream& operator<<(const char* text) { output(text); return *this; } }; int main() { minified_output_stream min_cout; min_cout << "A\n"; return 0; } And found that the binary which used this "imitation cout" only allocated 1 kilobyte of … -

Why overload arithmetic operator minus has conflict with valgrind?
While implementing operator overloading for the class of decimal numbers, I ran into a problem. I made this operator constant, since none of the parameters change. But Valgrind gives the following problem, as I understand it, the problem is related to the disruptor. void Seven::resizeArrayMinus() { unsigned char* tmp = new unsigned char[_size - 1]; std::memcpy(tmp, _array, (_size - 1) * sizeof(unsigned char)); delete this->_array; _array = tmp; _size--; } And what say valgrind: ==10049== Mismatched free() / delete / delete [] ==10049== at 0x484BB6F: operator delete(void*, unsigned long) (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so) ==10049== by 0x109CE4: Seven::resizeArrayMinus() (in /mnt/c/oop_lab/lab2/lab2) ==10049== by 0x10A4CE: Seven::operator-(Seven const&) const (in /mnt/c/oop_lab/lab2/lab2) ==10049== by 0x10A3A3: Seven::operator-(Seven const&) const (in /mnt/c/oop_lab/lab2/lab2) ==10049== by 0x109471: main (in /mnt/c/oop_lab/lab2/lab2) ==10049== Address 0x4dd6160 is 0 bytes inside a block of size 4 alloc'd ==10049== at 0x484A2F3: operator new[](unsigned long) (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so) ==10049== by 0x10965F: Seven::Seven(unsigned long const&, unsigned char) (in /mnt/c/oop_lab/lab2/lab2) ==10049== by 0x10A3F8: Seven::operator-(Seven const&) const (in /mnt/c/oop_lab/lab2/lab2) ==10049== by 0x10A3A3: Seven::operator-(Seven const&) const (in /mnt/c/oop_lab/lab2/lab2) ==10049== by 0x109471: main (in /mnt/c/oop_lab/lab2/lab2) ==10049== If you remove the constant value from the operator, the problem disappears -
