Is it a good idea to build a job search engine using Django & Apache Solr & React.js (for mobile apps)?
I'm an absolute beginner in python & programming so... be gentle 📷 I want to build a job search engine using: A. For BackEnd: Django (for secured login, optimized urls, ORM etc, clean & organized working environments) Apache Solr (for the job postings because I need a very fast search tool as I expect to be, HOPEFULLY, very many simultaneous search requests from a lot of simultaneous users), PostgreSQL (for storing CV's, as I don't expect CV's database to face very many simultaneous searches, also for storing metadata and other data that is not heavily searched for) B. For FrontEnd: HTML 5, CSS3, Bootstrap 4,JavaScript, React.js to build MobileApps for Ios and Android smartphones Now... thing is that, besides other questions, I have little if any ideea how to connect Django and Apache Solr... there little if any documentation... so, I really need all the help you may spare... any advice & help is welcome ! For those who have experience working with Django & Apache Solr: is it worth it? Does it suit a very fast & reliable multiple simultaneous concurrent searches with a lot of users searching for the same job posting in the same time? Because I … -
initdb: error: could not create directory "./PostgreSQL": Permission denied
It is my first time setting up a database (postgresql 12) on my windows 8.1 It's been 4 days of struggling to find a solution from many related questions in this field but not successful to find the answer (whether I didn't understand them or they didn't work in my case). So, here, I will explain, step by step, what I did and what errors I got in each phase (They may not affect each other but I mention all the errors): When I installed PostgreSQL, at the end of the process I got this error: "Failed to load SQL modules into the database cluster" I reinstalled twice it but it seemed to pop up every time. Here, in this post, I found somebody who faced the same problem, but I didn't technically understand what is the solution, unfortunately: Failed to load sql modules into the database cluster during PostgreSQL Installation. thus, I just skipped it and everything seemed okay. Then I set the PATH in advanced system settings-->Environment variables (in both user variables and system variables boxes) like this: ";C:\Program Files\PostgreSQL\12\bin;C:\Program Files\PostgreSQL\12\lib" After this step, I opened a terminal using ctrl+R and entered cmd.exe then entered these codes: > … -
