Any good ideas to learn the scales?

You might want to give a little study into the Circle of Fifths and how it relates to key signatures, chord progressions and the Relative Minors of those chords.  Those chord shapes contain and identify the colors (notes),  you have in your "palette"  at your disposal to paint your improvisation with..... the rest is practice, and learning how to transition between them.

The one thing that really helped me with scale is starting with the major C scale with one finger on one string. Go up and down, and try to sing —yes, sing, or, well, mumble— the notes. After you're pretty much sick of it and know it almost by ear, instead of going for another scale or another key, just start doing it in a mode. Again, key of C one finger, one string. This time, try to hear the difference between the notes that make the mode. For example, you can emphasize the 4th when doing Lydian, since this is the one that is different when compared to the major scale. This will give you a truly deep understanding of the modes and their different sounds. You will develop a really good ear in record time doing this.
I started doing it after more than 10 years of playing and I gained much more musical ear than in those 10 years just by doing this for a few weeks.

Experimenting with different patterns of notes     

Begin by learning the essential major and minor scopes: Start with the C major and A minor scopes, as they contain no sharps or pads. Work on playing them on your instrument routinely to fabricate muscle memory and find out more about the examples.

Make use of scale exercises: Use scale practices that consolidate different finger examples and arrangements to foster aptitude and coordination. There are various assets accessible, including books, online instructional exercises, and portable applications that give scale activities to different instruments.

Perform scales in a variety of keys: Explore additional keys gradually once you are familiar with the fundamental scales. You will gain a better understanding of how scales are constructed and improve your ability to navigate various musical compositions as a result of this.

Integrate scale practice into your everyday daily schedule: Commit a part of your training time to scales consistently. Consistency is critical, as a normal practice will build up your insight and work on your specialized abilities over the long haul.

Apply scales to music: As you become more capable with scales, have a go at integrating them into genuine melodic pieces. Search for melodies or sytheses that conspicuously highlight explicit scales and use them as a chance to apply your insight and investigate different melodic settings. This will help you understand how scales are used in music and make practicing them more interesting.
