The extensions list had been unmaintained for *years*, and the "approved" marking had lost meaning with many extensions on the list being unmaintained or deprecated in favor of other extensions. It was just too much of a hassle to keep up, and was lending a lot of weight to a very small subset of old extensions. PyPI has a "Framework :: Flask" classifier now, which extensions should use. I may bring the extension list back at some point, but I'd want it to be part of the Pallets Lektor site, and to be generalized to extensions for any of the Pallets projects. -------------- next part -------------- An HTML attachment was scrubbed...

The problem with your approach is that your else branch will trigger if a POST operation is in place, but form validation fails. In such a case, right now you drop user data and change it to the data stared in ir. If you have multiple SQLAlchemy models you may also want to look into the wforms-sqlalchemy package.

Message-ID: <042301d56b66$9dcf1c50$d96d54f0$@gmail.com> Hello all, I am sure this is something simple and I am overlooking the cause of the problem. I am new to JavaScript programming and accessing data using JSon via Python. I am not a professional developer and doing this for interest sake and learning more about programming. I am creating a personal budget program for my own use using Python flask and JavaScript. The JavaScript is going to handle get and post requests. The get request is to retrieve SQL Queries in a dict or array format. Contained in the dict will be dates, strings, integers and floats only. The date is formatted in yyyy-mm-dd format. The test script I am using does not contain dates at this stage. Once I work out the cause of my issue,. then I will be modifying other functions which the query results will include dates in the Json sserialised string. The prime issue is why my JavaScript code is not retrieving the data from my flask app. The 2nd issue is why I am getting a encoding file type error. The other parts of my flask app which does not involve JavaScript work fine. Examples I have seen have the script in the HTML code and they are using ginger and flask functions to provide the URL to the JavaScript. I have done this as well with the same errors seen in the chrome debug output. I have used an absolute and relative paths with the same failure. This has been done in the JavaScript file or within the HTML code. Below is the error messages: error messages from Firefox console: WarningThe script from "http://localhost:5000/static/test_json.js" was loaded even though its MIME type ("text/plain") is not a valid JavaScript MIME type. localhost:5000 ErrorSyntaxError: missing { before function body test_json.js:31:57 WarningThe script from "http://localhost:5000/static/Accordion.js" was loaded even though its MIME type ("text/plain") is not a valid JavaScript MIME type. localhost:5000 Chrome development console: test_json.js:31 Uncaught SyntaxError: Unexpected token ) :5000/favicon.ico:1 Failed to load resource: the server responded with a status of 404 (NOT FOUND) 1. I cannot find any syntax code in the test_json.js file. 2. Do not understand why Firefox is complaining about the file type when Chrome does not. I am getting this for both .js files. 3. The Chrome error is telling me it cannot find the data request source. If I put the absolute path of "http://localhost/transactions_summary_report" into Firefox. The data comes up as a tree which you can navigate. In the Javascript I have used the same absolute path where "/transactions_summary_report" is currently with no difference with error messages. If I put the absolute path into the browser address bar, the Json data is loaded. I do not know if this is an JavaScript error or python. I have even used known working JavaScript examples with the same result. Below is the current version of the code. JavaScript code for test_json: /* standard Ajax xhr function */ function getHTTPObject() { var xhr; if (window.XMLHttpRequest) { // check for support // if it's supported, use it because it's better xhr = new XMLHttpRequest(); } else if (window.ActiveXObject) { // check for the IE 6 Ajax // save it to the xhr variable xhr = new ActiveXObject("Msxml2.XMLHTTP"); } // end if return xhr; } function ajaxCall(dataUrl, callback) { /* use our function to get the correct Ajax object based on support */ var request = getHTTPObject(); request.onreadystatechange = function () { if (this.readyState == 4 && this.status === 200) { // save the ajax response to a variable var tableData = JSON.parse(request.responseText); // make sure the callback is indeed a function before executing it if (typeof callback === "function") { callback(tableData); } // end check for function } // end ajax check } // end state check function request.open("GET", dataURl, true); request.send(); } // end function for loading ajax data ajaxCall ("/transactions_summary_report", function(data)) { console.log(data); }; The python flask view code: import re, csv, glob, os from datetime import datetime from flask import render_template, flash, redirect, url_for, request, jsonify, json, Response from app import app, db from app.forms import * from app.models import * from sqlalchemy import extract @app.route('/', methods=['GET']) @app.route('/index', methods=['GET']) def index(): tables = Accounts.query.all() return render_template('index.html', title='Budget Program Main Page', tables = tables) @app.route('/transactions_summary_report') def transactions_summary_report(): report = [] # array of dicts. # loop through all the categories. for row in SubCategories.query.join(Categories).group_by(SubCategories.category_id).all (): # create the dict to store the total of each sub-category and grand total. record = {'Category':'', 'Totals':[], 'grand_total':0} record['Category'] = row.categories.category # assigning the current category # now loop through all the sub-categories and total the values.

That looks like an invocation of "ajaxCall", passing a string, and whatever "data" is after I'm guessing a type coercion to function. I don't know where "data" is coming from. However, IF that IS an invocation, what is the { console.log(data); }; supposed to be? Are you trying to pass an anonymous function? Maybe you want ajaxCall ("/transactions_summary_report", function (data) { console.log(data); }; ); to make the stuff inside {} the body of the anonymous function. AH! there is a help... If I remove all the blank lines from your source (it would help, in the future, if you adjust your posting client to NOT double space when you paste code... -=-=-=- /* standard Ajax xhr function */ function getHTTPObject() { var xhr; if (window.XMLHttpRequest) { // check for support // if it's supported, use it because it's better xhr = new XMLHttpRequest(); } else if (window.ActiveXObject) { // check for the IE 6 Ajax // save it to the xhr variable xhr = new ActiveXObject("Msxml2.XMLHTTP"); } // end if return xhr; } function ajaxCall(dataUrl, callback) { /* use our function to get the correct Ajax object based on support */ var request = getHTTPObject(); request.onreadystatechange = function () { if (this.readyState == 4 && this.status === 200) { // save the ajax response to a variable var tableData = JSON.parse(request.responseText); // make sure the callback is indeed a function before executing it if (typeof callback === "function") { callback(tableData); } // end check for function } // end ajax check } // end state check function request.open("GET", dataURl, true); request.send(); } // end function for loading ajax data ajaxCall ("/transactions_summary_report", function(data)) { console.log(data); }; -=-=-=- Makes the line ajaxCall(... #29, and column 57 is the second ")". And yes, that fits the error message in that the ")" is being seen as what would be the body of the function definition which is lacking the "{" to start it. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed at ix.netcom.com http://wlfraed.microdiversity.freeddns.org/ _______________________________________________ Flask mailing list Flask at python.org https://mail.python.org/mailman/listinfo/flask From stappers at stappers.nl Mon Sep 16 01:21:51 2019 From: stappers at stappers.nl (Geert Stappers) Date: Mon, 16 Sep 2019 07:21:51 +0200 Subject: [Flask] Cannot run debug mode In-Reply-To: <039001d56c1a$e08db330$a1a91990$@gmail.com> References: <039001d56c1a$e08db330$a1a91990$@gmail.com> Message-ID: <20190916052151.qyoakt5ypy6tg5cx@gpm.stappers.nl> On Mon, Sep 16, 2019 at 09:11:14AM +1000, mhysnm1964 at gmail.com wrote: > All, > > Windows 10, Python 3.6. > > > > I am having an issue with my flask app and do not understand why it does not > work.

Our webserver is Nginx but this should be possible with other but we have it pass off requests for some path, /api for example, to another upstream, a host and port. So we have multiple apps serving different parts of the site. This means that we can take down the upstream that serves the web front end without touching the /api feed. If necessary these can live on different hosts allowing you to upgrade the horsepower behind a given path simply by changing the host of the upstream and reloading the nginx configuration -------------- next part -------------- An HTML attachment was scrubbed...

I hope you didn't take offense to what I said. Yeah, it's going to take a lot of pounding on the keyboard, and business requirements and logic is most of the battle. If you want to look into "trendy" cool things right now, which I actually like to do. You can build the frontend via React or Angular, and have flask serve all the API's. I would separate all the different API's into blueprints. At first, I would just bundle all the blueprints together for the sake of actually getting things done. Afterwards, You can break the API's up into its own services really easily. ~Jonathan C.

Business logic I got , and If need to be I can logic scrape those using python. Most of the time, ERP / Accounting applications are pretty boring - no pretty, pretty pictures, nekid pictures, panoramic vista views, or music in them , just boring boring static type stuff. Dynamic stuff comes pretty much during reporting or report / posting , but even that is fairly structured. *Ben Duncan* DBA / Chief Software Architect Mississippi State Supreme Court Electronic Filing Division On Thu, Sep 26, 2019 at 8:37 AM Jonathan Chen wrote: > Okay, I just wanted to make sure that you understood its a big task.

Now, how is the procedure I need to do if the data fails SERVER validation? For example, it passes 'form.validate()" but testing within that 'if' reveals bad data. I want to keep the existing data in the form, but reject the form because some value was not correct, and set a error message and re display the form ...
