I need to get data from a bootstrap modal input. I'am using the following code :
#app.route('/rejets_modeles', methods=("POST","GET"))
def rejets_modeles():
{code}
if request.method == 'POST':
uname = request.form['uname']
print("----")
print(uname)
return render_template ('rejets_modeles.html', tables=[df.to_html(table_id = 'rejets_modeles')], titles=df.columns.values, header="true")
And here is my HTML code
<form action="POST">
<div class="modal-body-modifs">
<p>Gestion du rejet : </p>
<label><b>NOM</b></label>
<input type="text" name="uname"></br>
<label><b>PRENOM</b></label>
<input type="text" name="uprenom"></br>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-default" data-dismiss="modal"> OK</button>
</div>
</form>
I don't even have the ("---") printed, that means that my 'POST' request isnt' interpreted. How can I fix that ? Thank you
It has to be method instead of action
<form method="POST">
In action you can set url to which it has to send form data - ie.
<form method="POST" action="/rejets_modeles">
but if you want to send to the same url then you don't have to set it.
Solved. The problem was data-dismiss="modal" in my input tag. If you delete this the modal will close and the form will be sent via POST request.

I'm trying to make a simple commenting system where someone can add their comment to a post and it'll show up without having to redirect them or refresh the page. This is what my code basically looks like:
def post_details(request):
details = {}
if request.method == "POST":
request.POST
# Function here for creating a new comment
details['new_comment'] = new_comment
details['post_details'] = post_details
else:
details['post_details'] = post
return render(request, 'post_details.html', details)
The post_details.html shows a post with comments below it along with a form that adds their comment. I tried to add a new block of code in the template file for new_comment and the issue is that when I add a new comment, it will update that part but adding another one won't show up.
I should also note that I have CSV files that store the post and comment details. In my models.py file, I have my classes and methods to read in the CSV files so the function I left out does update the file with the comments. I'm trying to do this without Javascript but I'm open to trying anything, just really want to solidify my understanding of requests. I hope this wasn't confusing.
You can use JavaScript (AJAX) in this situation.
Create a base division in your template for showing your comments.
Then create an input form field for user to write comment.
Give the submit button id such as "addcomment" in my case.
Create the below ajax function with proper input values.
AJAX Function in JAVASCRIPT
$('#addcomment').click(function(){
// Taking_username_from_input_field_with_id_username.
var user = $('#username').val();
var usercomment = $('#usercomment').val(); // Taking_comment_from input_field_with_id_usercomment.
var csr = "{{csrf_token}}"; // Creating CSRF Token
$.ajax({
url: "{% url 'savecomment' blog.blog_id %}",
method:"POST",
data:{
user:user,
usercomment:usercomment,
csrfmiddlewaretoken:csr
},
success:function(data){
form.reset(); // resetting form values.
var output = "";
output =` <div class="comment">
<div class="comment-header d-flex justify-content-between">
<div class="user d-flex align-items-center">
<div class="image"><i class="fa fa-arrow-right"></i></div>
<div class="title"><strong>${data.user}</strong><span class="date">${data.date}</span></div>
</div>
</div>
<div class="comment-body">
<p>${data.comment}</p>
</div>
</div>`
$('.post-comments').append(output); // Appending data_in existing values which loaded_in first run.
//for_updating commentcount
var commentcount = data.number_of_comments;
$('.no-of-comments').replaceWith(`<span class="no-of-comments">(${commentcount})</span>`);
}
});

I am trying to capture HTTP form data using Python and Flask, but I keep getting "method not allowed" error. I have been trying to figure out why for some time with no luck. Here is what my code looks like:
#app.route("/add_recipe")
def addrecipepage():
if request.method=="post":
print ("Successful post request") # Just testing if code is working so far
return render_template("add_recipe.html")
and the HTML code:
<form id="contact" action="browseAll" method="post">
<div class="row">
<div class="col-md-6">
<fieldset>
<input name="name" type="text" class="form-control" id="name" placeholder="Recipe Name..." required="">
</fieldset>
<div class="col-12">
<textarea name="demo-message" id="recipeText" placeholder="Enter Ingredients & Instructions Here" rows="15"></textarea>
</div>
<div class="col-md-12">
<button type="submit" id="form-submit" class="button">Add The Recipe!</button>
<button id="uploadPhotoButton">Upload A Photo!</button>
</div>
</form>
When I click on the submit button, I get a HTTP 405 Method Not Allowed error. Anybody have any ideas as to why after looking at this? "browseAll" is another HTML page that I created an endpoint for in my app.py file. The same error gets thrown even if I don't specify an action though.
You are doing a POST (your form has method = "post") but your route does not have a post method attached to it. When you define a route without attaching a method, it defaults to GET. You need to do this
#app.route("/add_recipe", methods =['GET', 'POST'])
Getting a 400, when trying to upload a file ad send other form elements to flask from html. Tried to use ajax, but that throws me an error as well.
Python:
#app.route('/prod_diff_result', methods=['POST', 'GET'])
def prod_diff_result():
try:
host = request.form['host-prod-iterator']
print(host)
if request.files['file']:
f = request.files['file']
f.save(secure_filename(f.filename))
HTML:
<div class="main-div">
<form action="/prod_diff_result" method="POST" enctype="multipart/form-data">
<div class="grid-container">
<div class="grid-item">
<span class="label label-default ">PROD</span><br>
<p>Iterator Host : <input type="text" class="form-control" id="host-prod-iterator" value="10.47.7.57"
required></p>
<input type="radio" name="data_fetch_type" value="file" onclick="showfile()">Upload File
<input type="file" name="file" />
<input type="radio" name="data_fetch_type" value="db"> Get from DB
<input type="submit" />
</div>
</form>
</div>
I want to be able send hostname and file back to flask error in one request and using one form.
It gives an error because you try to access a form field that it cannot find, and assumes that somehow the request was bad, because it didn't include a required form field. You are trying to access:
host = request.form['host-prod-iterator']
However you have simply not given it a name in your HTML. If you give it a name, it should work:
<p>Iterator Host :
<input type="text" class="form-control" name="host-prod-iterator" id="host-prod-iterator" value="10.47.7.57" required>
</p>
I am attempting to return data from a HTML form with a POST request using Flask. For some reason I get a 400 Bad Request error. Looking at Chrome Dev Tools, I can see that all of the form fields with the input tag are part of the post request. The select tag with the dropwdown list is not being captured and I think this is creating the error. Anyone know why the select tag is not being captured in the post request? Any help much appreciated.
Here is the HTML form:
<label for="vendor">Select Vendor</label>
<div class="flextable p-b" style="padd">
<div class="flextable-item">
<select class="selectpicker" data-live-search="true" form="addInvoice" name="vendor" id="vendor">
<option>Jack Jaffa & Associates</option>
<option>Jacobs/Doland/Beer LLC</option>
<option>Jenkins & Huntington Inc.</option>
<option>Joseph J. Blake & Associates, Inc.</option>
<option>Langan (Geotechnical)</option>
<option>Madison Realty Capital</option>
<option>McNamara Salvia, Inc</option>
<option>Metropolis Group, Inc</option>
<option>National Grid</option>
</select>
</div>
<div class="flextable-item">
<button type="button" class="btn btn-xs btn-primary-outline">Add vendor</button>
</div>
<label for="invoice_number">Invoice Number:</label>
<input type="text" class="form-control p-b" placeholder="Every vendor invoice # must be unique" name="invoice_number" id="invoice_number">
<label for="invoice_amount">Amount:</label>
<input type="text" class="form-control p-b" placeholder="$0.00" name="invoice_amount" id="invoice_amount">
<label for="invoice_amount">Description:</label>
<input type="text" class="form-control p-b" placeholder="$0.00" width="100%" name="description" id="description">
<div class="spacer"></div>
<div class="flextable">
<div class="flextable-item">

</div>
<div>
<div class="flextable-item">
<div class="input-group">

<span class="icon icon-calendar"></span>
</span>
<input type="text" value="01/01/2015" class="form-control" data-provide="datepicker" style="width: 200px;" name="date_received" id="date_received">
</div>
</div>
</div>
</div>
</div>
<div class="modal-actions p-t-lg">
<button type="button" class="btn-link modal-action" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn-link modal-action" id="submit" >
<strong>Save + Continue</strong>
</button>
</div>
</form>
Here is the Flask python route:
#app.route('/add_invoice', methods=['GET', 'POST'])
def add_invoice():
""" Method for capturing form data to add invoice items to database"""
if request.method == 'POST':
find_cost_code = 7777 # eventually need code to lookup cost-code from POST request
print request.form['invoice_number']
print request.form['invoice_amount']
print request.form['description']
print request.form['vendor']
print request.form['date_received']
return "This is a test"
ADDED INFO:
So if I remove this line, the bad request error goes away:
print request.form['vendor']
This is because the "vendor" field is the only one in the html form that uses a select tag for input and that data is not catpured in the post request dictionary (which i can see in Chrome Dev Tool). The POST request is missing the field associated with the select tag. Not sure how to capture the select tag in the form data...
I've faced this issue many time when dealing with flask form, I think the solution is to enable csrf token protection :
according to this you need to initialise and enable it for you app!
Most of time error 400 is due to missing CSRF token.
you can do it as :
from flask_wtf.csrf import CSRFProtect
csrf = CSRFProtect(app)
for initialisation
and in your form add:
<input type="hidden" name="csrf_token" value="{{ csrf_token() }}"/>
hope it will help!!
feel free to edit.
form="addInvoice"
This attribute as part of my HTML form markup was what caused the error. I'm not sure exactly why but when it is removed, the error goes away.
(Thanks for your help above in trying to look into this.)
You need getlist to capture select.
My goal is to run python function when a user clicks on a button within a form on my web page, when the argument is taken from textarea HTML element.
The following html code is my form with button within and is part of django application.
<div id="contact_form" class="col_400 float_l">
<form id="demoForm" name="contact" >
<label for="text">Your Review:</label>
<textarea id="text" name="text" rows="0" cols="0" class="required"></textarea>
<div class="cleaner_h10"></div>
<input type="button" onclick="return Button1_onclick()" class="submit_btn float_l" name="submit" id="predictSentBtn" value="Predict" />
</form>
</div>
I looked on django.forms and django.forms.widgets, but still don't understand how to "link" between existing html elements and python objects.
This should help:
<div id="contact_form" class="col_400 float_l">
<form id="demoForm" name="contact" >
<label for="text">Your Review:</label>
<textarea id="needid" name="needid" rows="0" cols="0" class="required"></textarea>
<div class="cleaner_h10"></div>
<input type="button" onclick="return Button1_onclick()" class="submit_btn float_l" name="submit" id="predictSentBtn" value="Predict" />
</form>
def function(request):
if request.method = 'POST':
print request.POST['needid'] # print request.POST.get('needid')
Try it ;)
