I am trying to render the file home.html. The file exists in my project, but I keep getting jinja2.exceptions.TemplateNotFound: home.html when I try to render it. Why can't Flask find my template?
from flask import Flask, render_template
app = Flask(__name__)
#app.route('/')
def home():
return render_template('home.html')
/myproject
app.py
home.html
You must create your template files in the correct location; in the templates subdirectory next to the python module (== the module where you create your Flask app).
The error indicates that there is no home.html file in the templates/ directory. Make sure you created that directory in the same directory as your python module, and that you did in fact put a home.html file in that subdirectory. If your app is a package, the templates folder should be created inside the package.
myproject/
app.py
templates/
home.html
myproject/
mypackage/
__init__.py
templates/
home.html
Alternatively, if you named your templates folder something other than templates and don't want to rename it to the default, you can tell Flask to use that other directory.
app = Flask(__name__, template_folder='template') # still relative to module
You can ask Flask to explain how it tried to find a given template, by setting the EXPLAIN_TEMPLATE_LOADING option to True. For every template loaded, you'll get a report logged to the Flask app.logger, at level INFO.
This is what it looks like when a search is successful; in this example the foo/bar.html template extends the base.html template, so there are two searches:
[2019-06-15 16:03:39,197] INFO in debughelpers: Locating template "foo/bar.html":
1: trying loader of application "flaskpackagename"
class: jinja2.loaders.FileSystemLoader
encoding: 'utf-8'
followlinks: False
searchpath:
- /.../project/flaskpackagename/templates
-> found ('/.../project/flaskpackagename/templates/foo/bar.html')

followlinks: False
searchpath:

-> found ('/.../project/flaskpackagename/templates/base.html')
Blueprints can register their own template directories too, but this is not a requirement if you are using blueprints to make it easier to split a larger project across logical units. The main Flask app template directory is always searched first even when using additional paths per blueprint.
I think Flask uses the directory template by default. So your code should be like this
suppose this is your hello.py
from flask import Flask,render_template
app=Flask(__name__,template_folder='template')
#app.route("/")
def home():
return render_template('home.html')
#app.route("/about/")
def about():
return render_template('about.html')
if __name__=="__main__":
app.run(debug=True)
And you work space structure like
project/
hello.py
template/
home.html
about.html
static/
js/
main.js
css/
main.css
also you have create two html files with name of home.html and about.html and put those files in templates folder.
If you must use a customized project directory structure (other than the accepted answer project structure),
we have the option to tell flask to look in the appropriate level of the directory hierarchy.
for example..
app = Flask(__name__, template_folder='../templates')
app = Flask(__name__, template_folder='../templates', static_folder='../static')
Starting with ../ moves one directory backwards and starts there.
Starting with ../../ moves two directories backwards and starts there (and so on...).
Within a sub-directory...
template_folder='templates/some_template'
I don't know why, but I had to use the following folder structure instead. I put "templates" one level up.
project/
app/
hello.py
static/
main.css
templates/
home.html
venv/
This probably indicates a misconfiguration elsewhere, but I couldn't figure out what that was and this worked.
If you run your code from an installed package, make sure template files are present in directory <python root>/lib/site-packages/your-package/templates.
Some details:
In my case I was trying to run examples of project flask_simple_ui and jinja would always say
jinja2.exceptions.TemplateNotFound: form.html
The trick was that sample program would import installed package flask_simple_ui. And ninja being used from inside that package is using as root directory for lookup the package path, in my case ...python/lib/site-packages/flask_simple_ui, instead of os.getcwd() as one would expect.
To my bad luck, setup.py has a bug and doesn't copy any html files, including the missing form.html. Once I fixed setup.py, the problem with TemplateNotFound vanished.
I hope it helps someone.
Check that:
the template file has the right name
the template file is in a subdirectory called templates
the name you pass to render_template is relative to the template directory (index.html would be directly in the templates directory, auth/login.html would be under the auth directory in the templates directory.)
you either do not have a subdirectory with the same name as your app, or the templates directory is inside that subdir.
If that doesn't work, turn on debugging (app.debug = True) which might help figure out what's wrong.
I had the same error turns out the only thing i did wrong was to name my 'templates' folder,'template' without 's'.
After changing that it worked fine,dont know why its a thing but it is.
You need to put all you .html files in the template folder next to your python module. And if there are any images that you are using in your html files then you need put all your files in the folder named static
In the following Structure
project/
hello.py
static/
image.jpg
style.css
templates/
homepage.html
virtual/
filename.json
When render_template() function is used it tries to search for template in the folder called templates and it throws error jinja2.exceptions.TemplateNotFound when :
the file does not exist or
the templates folder does not exist
Create a folder with name templates in the same directory where the python file is located and place the html file created in the templates folder.
Another alternative is to set the root_path which fixes the problem both for templates and static folders.
root_path = Path(sys.executable).parent if getattr(sys, 'frozen', False) else Path(__file__).parent
app = Flask(__name__.split('.')[0], root_path=root_path)
If you render templates directly via Jinja2, then you write:
ENV = jinja2.Environment(loader=jinja2.FileSystemLoader(str(root_path / 'templates')))
template = ENV.get_template(your_template_name)
After lots of work around, I got solution from this post only,
Link to the solution post
Add full path to template_folder parameter
app = Flask(__name__,
template_folder='/home/project/templates/'
)
My problem was that the file I was referencing from inside my home.html was a .j2 instead of a .html, and when I changed it back jinja could read it.
Stupid error but it might help someone.
Another explanation I've figured out for myself
When you create the Flask application, the folder where templates is looked for is the folder of the application according to name you've provided to Flask constructor:
app = Flask(__name__)
The __name__ here is the name of the module where application is running. So the appropriate folder will become the root one for folders search.
projects/
yourproject/
app/
templates/
So if you provide instead some random name the root folder for the search will be current folder.

I am developing a rather big project in pyramid. I used django before. I really like the way it structures the project and encapsulate functionality into apps. I would like to achieve same structure with pyramid. I know pyramid is very flexible to get this, but I need some help to achieve same structure with loose coupling. The project structure should look something like:

Any suggestions?
Since Pyramid makes no assumptions about your package structure in the first place, any way you divide your app ends up being fairly similar in configuration. However, if you're breaking your app into some distinct packages, you can (optionally) take advantage of the config.include() directive to include each package into your main config.
For example:
# myapp/__init__.py (main config)
def main(global_config, **settings):
config = Configurator(...)
# basic setup of your app
config.include('pyramid_tm')
config.include('pyramid_jinja2')
# add config for each of your subapps
config.include('project.app1')
config.include('project.app2')
# make wsgi app
return config.make_wsgi_app()
# myapp/app1/__init__.py (app1's config)
def includeme(config):
config.add_route(...)
config.scan()
# myapp/app2/__init__.py (app2's config)
def includeme(config):
config.add_route(...)
config.scan()
In each of your subapps, you can then define views/models/etc.
In general you might want to create your SQLAlchemy (or other DB) session in the common setup, as likely your different apps are all using the same engine.
I have implemented a global appIncluder function which is imported as includeme with the init.py of the package to be included.
includeme (ApplicationIncluder) receives the config object, so it is then easy to use config.package and its variables/methods/classes (present in the same init.py and submodules.
Thanks a lot for this idea!
The code:
project: 'foo'
apps to be deployed in foo.foo.apps directory
Structure:
foo
|-foo
|- __init__.py
|- appincluder.py
|-apps
|-test
|- __init__.py
|- views.py
|- templates
|- test.jinja2
foo/foo/init.py:
config.include('foo.apps.test')
foo/foo/appincluder.py
def appIncluder(config):
app = config.package
prefix = app.prefix
routes = app.routes
for route,url in routes.items():
config.add_route(route,prefix + url)
config.scan(app)
log.info('app: %s included' % app.__name__)
foo/foo/apps/test/init.py
from foo.appincluder import appIncluder as includeme
prefix = '/test'
routes = {
'test': '/home'
}
foo/foo/apps/test/views.py
from pyramid.view import view_config
#view_config(route_name='test', renderer='templates/test.jinja2')
def test(request):
return {}
I hope it helps someone.
