I would like to create a href link in Odoo pointing to external file based on field value .....

for example: <field name="item_id"/> value of this field is 123456789012

at the end I would like to have a link for example: 'href="localhost/images/123456789012.png"'

and then add widget image to display selected picture .....

Is it possible ? If so, how can i do it ?

(easiest way)

Create def and then append 'link','.ext' ?

How should it look like ?

I searched on internet but I couldn't find any examples :(

So far i tried to use (modified) widget="html" and it create a link but because is already one widget added i can't add another one :)

so i need create a link then add widget="image" or custom widget to show image in form :)

I've managed to do it partially, it shows me a placeholder from the same location but it won't display a selected image ;(

........

Ahahaha I got it, it works but .... silly me python generates incorrectly a string  :)

at the end i'm getting a string which looks like this: "(u'360651041248', '.jpg')" how can I get rid of unwanted chars to get only '360651041248.jpg' ?

I managed to clear string and now is perfect but somehow Odoo instead /web/src/img/myimages/ trying to find an image directly in //localhost:8069/image.jpg

What the hell ?

Why ? 

Everything seems to be ok but it won't work ...

<pre>

instance.web.form.FieldPCTable = instance.web.form.FieldBinary.extend({

template: 'FieldBinaryImage',

placeholder: "/web/static/src/img/pctables/placeholder.jpg", ### here is the link to the placeholder image which works perfectly

render_value: function() {

var self = this;

var url;

if (this.get('value') && !instance.web.form.is_bin_size(this.get('value'))) {

url = this.get('value');

} else if (this.get('value')) {

var id = JSON.stringify(this.view.datarecord.id || null);

var field = this.name;

if (this.options.preview_image)

field = this.options.preview_image;

url = 'data:image/png;base64,' + this.session.url('/web/static/src/img/pctables/', { ### here is a folder where image is located

model: this.view.dataset.model,

id: id,

field: field,

t: (new Date().getTime()),

});

and at the end I'm getting http://localhost:8069/image.jpg ..... WHY !?!?!?!

I think I found the culprit ;)
