I am implementing an app using Flask and I am trying to display the content of text files I put in log directory. So i have done this:
@app.route('/files', methods = ['GET'])
def config():
if 'username' in session :
path = os.path.expanduser(u'~/path/to/log/')
return render_template('files.html', tree=make_tree(path))
else:
return redirect(url_for('login'))
def make_tree(path):
tree = dict(name=os.path.basename(path), children=[])
try: lst = os.listdir(path)
except OSError:
pass #ignore errors
else:
for name in lst:
fn = os.path.join(path, name)
if os.path.isdir(fn):
tree['children'].append(make_tree(fn))
else:
tree['children'].append(dict(name=name))
return tree
in my html page files.html:
<title>Path: {{ tree.name }}</title>
<h1>{{ tree.name }}</h1>
<div class="accordion-heading" >
<div class="accordion-toggle" >
<a data-toggle="collapse" data-target="#files_list" href="#files_list">
<b>
<ul>
{%- for item in tree.children recursive %}
<div class="well well-sm"> <li>{{ item.name }} </div>
{%- if item.children -%}
<ul>{{ loop(item.children) }}</ul>
{%- endif %}</li>
{%- endfor %}
</ul>
</b></div>
</a>
</div>
This only displays the names of the files inside my log directory but I am not able to display the content of the files. I thought maybe I can use something like:
import fnmatch
def display_files():
for dirpath, dirs, files in os.walk('log'):
for filename in fnmatch.filter(files, '*.*'):
with open(os.path.join(dirpath, filename)) as f:
file_contents = f.read().strip()
print file_contents
return render_template('files.html',title="index",file_contents=file_contents)
Any help please??
You probably can read contents of your file and pass it to template in make_tree
function like that:
def make_tree(path):
tree = dict(name=os.path.basename(path), children=[])
try: lst = os.listdir(path)
except OSError:
pass #ignore errors
else:
for name in lst:
fn = os.path.join(path, name)
if os.path.isdir(fn):
tree['children'].append(make_tree(fn))
else:
with open(fn) as f:
contents = f.read()
tree['children'].append(dict(name=name, contents=contents))
return tree
and just add <pre>{{ item.contents }}</pre>
to the place where you want to display the contents of the file. For example, here:
{%- for item in tree.children recursive %}
<div class="well well-sm">
<li>
{{ item.name }}
<pre>{{ item.contents }}</pre>
{%- if item.children -%}
<ul>{{ loop(item.children) }}</ul>
{%- endif %}
</li>
</div>
{%- endfor %}
This is kind of ugly, but it should show the correct data.
