openerp - Usage of Search Attribute in field tag in openerp7 -

-

can tell me use of search attribute in field tag.

sample documentation below

<field name="partner_id" search="[]" model="res.partner"/>

sample openerp code below

 <field name="fields_id" search="[('model','=','res.partner'),('name','=','property_account_receivable')]"/>  # account/demo/account_minimal.xml   <field model="res.country.state" name="state_id" search="[('code','ilike','ca')]"/> # base/res/res_partner_demo.xml   <field name="account_debit" search="[('code', 'like', '4540%')]"/> # l10n_be_hr_payroll_account/l10n_be_hr_payroll_account_data.xml

documentation explanation below

the search attribute allows find record associate when not know xml id. can specify search criteria find wanted record. criteria list of tuples of same form predefined search method. if there several results, arbitrary 1 chosen (the first one)

i having prob in understanding how above works. can me out how needs used. possible give dynamic search values global filter. time.

as per knowledge ids = self.search(cr, uid,[ '|', ('partner_id', '!=', 13),'!', ('name', 'ilike', 'abc'), ]) search partner id isn't 13 , ignore name of abc fetch record non-abc partner shops + partner 13

for prefix operators: '&' (default), '|', '!'

for operator =, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right

hope understand.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
